![]() ![]() After removing the mount command from /etc/fstab the system booted into the normal shell without a problem, but of course without the RAID volume mounted.Īfter boot I ran sudo mount /dev/sda1 /data and got the error mount: special device /dev/sda1 does not exist. Debugging eventually led me to discover that it was failing to mount the RAID volume. Originally when the server rebooted the system was dropped into the Dracut emergency recovery shell after a "dracut timeout: failed to initialize the filesystem" error. I don't mind saying I'm at a loss as to how to even approach this, and there's only so many ways I can google "partition not assigned partition number". I'd also accept answers that simply suggest more research I can do. This server was scheduled to be decommissioned in a few months anyway, so root-cause analysis isn't a concern, but data recovery is. I am looking for advice to get the drive mounted and the data copied off of it. After a recent reboot of the server, the server can no longer mount the partition. The RAID volume has a single EXT4 partition on it. The software quickly reconstructs RAID 5 volumeīased on provided parameters.I have a CentOS 7.5 server with an array of 4x 3TB WD Reds in hardware RAID 5.The software intelligently rebuilds a few probable RAID constructions, which Required parameter drop-downs if you don’t know or remember the required RAID Size Select Parity Order/Rotation and then select the parity repetition or delay from respective dropdowns. Sector in the text box if it’s not listed in the checklist box Then choose one or more probable start sector(s) or add desired start Probable start sectors’ checkbox if you don’t know or remember the start Hard disks to arrange them in the same sequence as they were in the RAID array Use the up/down arrow buttons beside the added.To ‘ Move hard drives up/down for disk order’ list box ![]() Click the Waffle icon at the top right and select ‘ Monitor Drive’ from the menu.īutton to select and move the RAID 5 hard disks listed under ‘ Select Hard drives to reconstruct RAID’.Step 2: Check Drive Health & SMART Statusįree download, Install, and run Stellar Data Recovery Technician software. You may also use SATA to USB converter cables. Steps to Recover Data from Unmounted or Failed RAID 5 Array Step 1: Disconnect Drives from the RAID 5 Arrayįollow the steps in the given order to reconstruct a RAID 5 volume for recovery safely:ĭrives from the array and connect them to a Windows system by using SATAĬonnectors. Reconstruct a fresh RAID 5 arrangement from scratch and restore your data. Once you get back your data from a RAID 5 volume, In such cases, you should recover data by using a RAID 5ĭata Recovery Technician. This happens due to some missing information The Drive Monitor or CrystalDiskInfo tool. Head to the rebuilding process, check the SMART status of all member disks. In most cases, it’s rebuilding or reconstructing the RAID array. And there is no way to get it back other than fixing When a RAID 5 volume fails to mount, the access to the data It may unmount or fail to mount due to multiple disk failure or logical errorĬrash, power surges or failure, malware/virus attack, and disk errors etc. However, a RAID 5 array protects against single disk failure Professionals and businesses as it’s the most affordable RAID array thatįacilitates faster read speed-equivalent to RAID 0-with redundancy.
