Could be worse I guess. You can see how much of each disk is used by each user share by clicking Compute... on the User Shares page, or Compute All button at bottom.

trurl Posted August 2 Share Posted August 2 Current parity looks OK so parity copy part of the parity swap should be fine. The reason I am asking about backups is because I am concerned disk2 might be a problem while rebuilding disk8 to the (will be) former parity disk. Disk2 is currently involved in emulating disk8 anyway whether used for copying emulated disk8 data or for disk8 rebuild, but might not be involved as much for just copying the data from emulated disk8 as it would be emulating the full disk8 for a rebuild.

sabarirjpm Posted August 2 Author Share Posted August 2 So you would like to backup the data in Disk 8 or in Disk 2 to begin with or both? Quote Link to comment
trurl Posted August 3 Share Posted August 3 Is all of it important and irreplaceable? Where would you copy it? Quote Link to comment
sabarirjpm Posted August 3 Author Share Posted August 3 Started taking the backups of Disk 8 currently and while it is in progress, see read errors in Disk 2. Attached the diagnostics. With this now, I am worried what would happen during the parity swap. Any suggestions? tower-diagnostics-20220803-1549.zip Quote Link to comment
trurl Posted August 3 Share Posted August 3 It has to read all the other disks to emulate the missing disk from the parity calculation, any problem reading all the other disks can cause problems with the emulation. The emulated data is what is being copied, and what would be rebuilt during parity swap. Where are you copying the data to? SMART report for disk2 seems to be getting worse. How much left to be copied? Quote Link to comment
sabarirjpm Posted August 3 Author Share Posted August 3 Am using one of the 12TBs(formatted as NTFS and added to a Windows PC) that I have and moving the data over the network. Another 120 GB pending to be copied across for disk 8 which is emulated and another 2TB of disk2 to be backed up. Thought of completing the emulated drive, do a parity swap and then replace the data drive disk 2. Now I think I need to backup the disk 2 before doing a parity swap. Correct me if I am wrong Quote Link to comment

sabarirjpm Posted August 3 Author Share Posted August 3 Will take the disk 2 backup. After the parity swap and rebuilding Disk8, while replacing the disk 2, I would like it to be in XFS how do I get it. According to the wiki, it will again be reiserfs. Eventually, would like every drive moved to xfs Quote Link to comment
trurl Posted August 3 Share Posted August 3 Parity doesn't know anything about filesystems, it is all just bits, a good rebuild can only result in those same bits, which represent that same filesystem and its files. You have to copy the data from reiserfs disks so you can reformat them as XFS Quote Link to comment
sabarirjpm Posted August 5 Author Share Posted August 5 Backing up the Disk 2 did not work as it threw continuous read errors and had to cancel. Proceeded without backup as it had mostly movies. Parity Swap, Disk 8 Rebuild done. It again had read errors while rebuilding Disk8. Swapped Disk2 with a 4TB drive and rebuilding is in progress. Attached are the logs after the rebuild of Disk8. Did I loose any data? tower-diagnostics-20220805-0617.zip Quote Link to comment
sabarirjpm Posted August 5 Author Share Posted August 5 Attached is the log after the Disk2 replacement with a 4TB. tower-diagnostics-20220805-1734.zip Quote Link to comment

sabarirjpm Posted August 6 Author Share Posted August 6 (edited) Thanks much. Have the following to-dos. 1. Move the data from newly added 4TB on to other disks using Unbalance plugin and convert the filesystem to xfs 2. Copy over the data/ backups available in the temporary 12TB drive that I had off the array and move it to unRAID 3. Use shrink-array to consolidate few disks 4. Convert the rest to XFS 4. Use one of the left over 2TBs after the consolidation as a cache disk.. Will keep posted on the progress. Thanks all along for getting my array back on shape Edited August 6 by sabarirjpm 1 Quote Link to comment
