Long story short, RAID systems take many hard disks and combine them into one logical unit.<\/p>\n<p>This increases reliability and\/ or performance and\/ or capacity.<\/p>\n<p>There are three main components to a RAID protocol:<\/p>\n<ol>\n<li><strong>Striping<\/strong>: Where a piece of data is split across multiple locations (<span style=\"text-decoration: underline;\"><em>drives<\/em><\/span>). This way, if one drive fails, the others are still accessible.<\/li>\n<li><strong>Mirroring<\/strong>: As the name suggests, this is where each drive in the array is mirrored (<span style=\"text-decoration: underline;\"><em>duplicated<\/em><\/span>). However, this usually halves the storage capacity of the array.<\/li>\n<li><strong>Parity<\/strong>: A complex operation involving XOM calculations (<span style=\"text-decoration: underline;\"><em>exclusive OM<\/em><\/span>). Parity ensures redundancy compliance at the expense of write speeds.<\/li>\n<\/ol>\n<p>Now, RAID 5, which is our focus for today, is a protocol that uses both striping and parity data writing algorithms.<\/p>\n<p>This makes it harder to <strong>rebuild RAID 5 without losing data<\/strong>, as compared to, say, RAID 1 which uses mirroring only.<\/p>\n<p>But first, let\u2019s understand what might create a situation, where you have to rebuild a RAID or <strong><a href=\"https:\/\/www.stellarinfo.co.in\/services\/raid-data-recovery.php\" target=\"_blank\" rel=\"noopener\">recover data from a RAID<\/a><\/strong> drive.<\/p>\n<ul>\n<li>In cases where a RAID array, such as RAID 5, is operating in a degraded mode due to a disk failure, it&#8217;s advisable to <span style=\"text-decoration: underline;\"><em>recover data before rebuilding<\/em><\/span>.<\/li>\n<li>This precaution is especially important if the RAID has been in this compromised state for an extended period, or if there are concerns about the health and longevity of the remaining disks.<\/li>\n<li>The reason is, the rebuild process is intensive and can stress the other drives, potentially leading to another failure.<\/li>\n<li>To mitigate the risk of data loss during the rebuild, it&#8217;s prudent to first secure and back up the existing data.<\/li>\n<li>This ensures that even if complications arise during the rebuild, critical data remains safeguarded.<\/li>\n<\/ul>\n<h2 style=\"text-align: justify;\"><strong id=\"srv2\">How To Recover Data From RAID Before Rebuild(s)?<\/strong><\/h2>\n<p>Here&#8217;s a step-by-step breakdown of &#8220;<strong>How to recover data from RAID before rebuild<\/strong>&#8220;:<\/p>\n<p><strong>1. Assess the RAID Status<\/strong><\/p>\n<p>Before taking any action, check the status of the RAID array using RAID management software or the RAID controller&#8217;s interface. Identify which disk(s) have failed.<\/p>\n<p><strong>2. Backup Existing Data<\/strong><\/p>\n<p>If the RAID is still accessible in a degraded mode, immediately backup all critical data to an<span style=\"text-decoration: underline;\"><em> external storage device or cloud storage<\/em><\/span>.<\/p>\n<p><strong>3. Use RAID Recovery Software<\/strong><\/p>\n<p>If the RAID is not accessible, consider using specialized <strong><a href=\"https:\/\/www.stellarinfo.co.in\/software\/windows-raid-recovery.php\" target=\"_blank\" rel=\"noopener\">RAID recovery software<\/a><\/strong>. These tools can help reconstruct the RAID parameters and retrieve data even from a degraded RAID.<\/p>\n<p><strong>4. Avoid Writing New Data<\/strong><\/p>\n<p>Do not write any new data to the RAID array until the recovery process is complete. Writing new data can overwrite lost data sectors, making recovery more challenging.<\/p>\n<p><strong>5. Consult with Experts<\/strong><\/p>\n<p>If you&#8217;re unsure about the recovery process or if the <span style=\"text-decoration: underline;\"><em>RAID recovery software<\/em><\/span> doesn&#8217;t yield results, consider consulting with data recovery experts who specialize in RAID configurations.<\/p>\n<p><strong>6. Initiate RAID Rebuild<\/strong><\/p>\n<p>Once you&#8217;ve secured your data, you can proceed with the RAID rebuild process by replacing the failed disk(s) and using the RAID management tools to rebuild the array.<\/p>\n<h2 style=\"text-align: justify;\"><strong id=\"srv3\">How To Rebuild RAID 5 Without Losing Data?<\/strong><\/h2>\n<p>Let us learn how to <strong>rebuild raid 5 without losing data<\/strong>.<\/p>\n<p>RAID 5 can easily handle one drive failing. However, if more drives fail, this could result in a complete loss of all data.<\/p>\n<p>Before we begin, note a major oversight that many people make when trying to <strong>rebuild RAID 5 without losing data<\/strong>:<\/p>\n<p>Remember that the file system on your new drive needs to match the rest of the drives.<\/p>\n<p>Even though your file system (<span style=\"text-decoration: underline;\"><em>NTFS, exFAT<\/em><\/span>, etc) is independent of the RAID level, this is a problem if you want to <strong>rebuild RAID without losing data.<\/strong><\/p>\n<p>RAID 5 uses <em>striping<\/em> which writes data across <em>multiple<\/em> disks. If you write data via striping to one NTFS drive and one exFAT drive, naturally there will be problems.<\/p>\n<p>This is why it is recommended to format the drive you are replacing to the same File Management System as the other drives in the RAID system. This is key if you want to <strong>rebuild RAID 5 without losing data.<\/strong><\/p>\n<p>Here are the <strong>best steps to rebuild a failed RAID 5 array<\/strong>:<\/p>\n<h3><strong>1. Find the Faulty Drive<\/strong><\/h3>\n<p>Identify which drive in the RAID 5 array isn&#8217;t working. Most times, there are signs or messages indicating the problematic drive.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-22116 aligncenter\" src=\"https:\/\/www.stellarinfo.co.in\/blog\/wp-content\/uploads\/2023\/09\/find-the-fault-drive-300x105.jpg\" alt=\"find the fault drive\" width=\"572\" height=\"200\" srcset=\"https:\/\/www.stellarinfo.co.in\/blog\/wp-content\/uploads\/2023\/09\/find-the-fault-drive-300x105.jpg 300w, https:\/\/www.stellarinfo.co.in\/blog\/wp-content\/uploads\/2023\/09\/find-the-fault-drive-150x52.jpg 150w, https:\/\/www.stellarinfo.co.in\/blog\/wp-content\/uploads\/2023\/09\/find-the-fault-drive.jpg 750w\" sizes=\"auto, (max-width: 572px) 100vw, 572px\" \/><\/p>\n<p><em><span style=\"text-decoration: underline;\"><strong>Note:<\/strong><\/span> RAID 5 is only designed to handle one drive failing.<\/em><\/p>\n<p>If two or more drives in your <span style=\"text-decoration: underline;\"><em>RAID 5 array have failed<\/em><\/span>, you need specialized help.<\/p>\n<p><em><strong><u>Important:<\/u><\/strong> Stellar DataRecovery can help, but more on that later.<\/em><\/p>\n<h3><strong>2. Replace the Damaged Drive<\/strong><\/h3>\n<p>Shut down the system and swap out the faulty drive with a new one that matches or is compatible with the others.<\/p>\n<p>It is important to note that most professional setups have <em>the same model of drives<\/em> in an array.<\/p>\n<p><em><strong><u>Important:<\/u><\/strong> It is advisable to replace the failed drive with the exact same make and model as the others in the RAID 5 array.<\/em><\/p>\n<h3><strong>3. Access the RAID Controller Configuration Utility<\/strong><\/h3>\n<p>Turn on the computer and access the RAID controller&#8217;s configuration utility during the startup process (usually by pressing specific keys).<\/p>\n<p>The keys you need to press are usually displayed when the computer is booting.<\/p>\n<p>The message will look something like: \u201c<span style=\"text-decoration: underline;\"><em>Please press Ctrl + R<\/em><\/span>\u201d to enter RAID Utility Editor.<\/p>\n<p>Now, in our example, we have used <strong>mdadm<\/strong> which is a Linux utility, but your raid utility could be OEM, so look carefully.<\/p>\n<p>In the screenshot above this point, the Synology utility tells you exactly which drive has failed.<\/p>\n<p>In this particular case, you can repair it directly from there after replacement.<\/p>\n<p><em><span style=\"text-decoration: underline;\"><strong>Important<\/strong><\/span><strong>:<\/strong> If you do not know how to enter the RAID Configurator, you can check the manufacturer\u2019s website.<\/em><\/p>\n<p>Just hit the search button (<span style=\"text-decoration: underline;\"><em>there will definitely be one<\/em><\/span>). Then, type in your RAID controller model number.<\/p>\n<h3><strong>4. Connect the New Drive to the RAID Array<\/strong><\/h3>\n<p>Inside the RAID controller utility, connect the recently replaced drive to the correct RAID 5 array slot.<\/p>\n<p>You can find which bay the drive needs to be installed inside your RAID configuration editor.<\/p>\n<p>Remember to check that the new drive has been accepted by the RAID configurator before moving on to step #5.<\/p>\n<p><em><strong><u>Important<\/u><\/strong>: If your drive bay has multiple empty spaces, place the faulty drive where the RAID CCU tells you to. You cannot just put it anywhere.<\/em><\/p>\n<p>This is a very important step if you want to <strong>rebuild RAID 5 without losing data<\/strong>.<\/p>\n<h3><strong>5. Initiate the Rebuilding Procedure<\/strong><\/h3>\n<p>RAID 5 uses parity as well as striping. The stored parity data allows the RAID controller to rebuild the missing drive. It is remarkably similar to a game of <span style=\"text-decoration: underline;\"><em>sudoku<\/em><\/span>, but that is an article for another day.<\/p>\n<p>For now, navigate through the internal menus in your RAID configurator, and locate an option related to repair.<\/p>\n<p>Select the array that you replaced the drive in, and confirm that you want to repair it.<\/p>\n<p>Begin the RAID rebuild process. The RAID controller will automatically start rebuilding the array using the existing data and parity information.<\/p>\n<p><em><strong><span style=\"text-decoration: underline;\">Note<\/span>: <\/strong>The screen will be different depending on what software your RAID CCU uses.<\/em><\/p>\n<h3><strong>6. [Optional]: Monitor the Progress of the Rebuild<\/strong><\/h3>\n<p>Keep an eye on the rebuild progress within the RAID controller&#8217;s interface. This procedure might take several hours depending on drive size and data amount.<\/p>\n<p>Important: If you are using enterprise-level storage, dedicated disk monitors could be a lifesaver in the future.<\/p>\n<p>They can tell you the health of a drive in real-time, as well as loads of other useful information.<\/p>\n<h3><strong>7. Ensure Uninterrupted Rebuild<\/strong><\/h3>\n<p>Avoid turning off the system or interrupting the rebuild process. Interruptions could result in data loss or corruption.<\/p>\n<h3><strong>8. Confirm Successful Rebuild<\/strong><\/h3>\n<p>After the rebuild is complete, verify that the RAID array is healthy again and that all data is accessible.<\/p>\n<p>And that&#8217;s it. Those were the <strong>best steps to rebuild a RAID 5 array.<\/strong><\/p>\n<p>You can use the steps above to:<\/p>\n<ol>\n<li><strong>Rebuild RAID 0 Without Losing Data<\/strong>,<\/li>\n<li><strong>Rebuild RAID 1 Without Losing Data<\/strong>, and<\/li>\n<li><strong>Rebuild RAID 5 Without Losing Data<\/strong>.<\/li>\n<\/ol>\n<p>RAID 0 <em>will<\/em> come with additional complications (<span style=\"text-decoration: underline;\"><em>because no Parity data<\/em><\/span>), but the process is essentially the same.<\/p>\n<p>Again though, this is a topic for another day.<\/p>\n<h2 style=\"text-align: justify;\"><strong id=\"srv4\">Rebuild RAID 5 With Two (Or More) Failed Drives<\/strong><\/h2>\n<p>Other than RAID 0, all other RAID configurations will come with at least one \u201c<span style=\"text-decoration: underline;\"><em>hot drive<\/em><\/span>\u201d.
