widdefmh Posted March 11, 2022 Share Posted March 11, 2022 (edited) I have two pools, the first is named Corsair1ssd and the second pool is named Corsair2ssd. I have a share called Corsair.mx500.1tb which has the following settings: Use cache pool (for new files/directories): Only Select cache pool: Corsair2ssd Despite the above settings the files in the share is written to both Corsair1ssd and Corsair2ssd pools? Why is that?? With the setting above it shoould only write to Corsair2ssd pool.... Edit: Also... My appdata-folder is set to only write to Corsair1ssd pool, but is written to both discs anyway.. Really weird.. Edited March 11, 2022 by widdefmh Quote Link to comment
JorgeB Posted March 11, 2022 Share Posted March 11, 2022 Probably both devices are still in the same pool, please post diagnostics to confirm. Quote Link to comment

Nope they are not in the same pool. What files from the diagnostic do you need? They have never been in the same pool. It is 2 Corsair MX 500 discs and the first disc is in Corsair1ssd pool and the other is in Corsair2ssd pool. Both pools are set to have 1 disc. I can see the following in the corsair share config: # Generated settings: shareComment="..." shareInclude="" shareExclude="" shareUseCache="only" shareCachePool="corsair2ssd" shareCOW="no" shareAllocator="highwater" shareSplitLevel="" shareFloor="0" shareExport="e" shareFruit="no" shareCaseSensitive="auto" shareSecurity="private" shareReadList="" shareWriteList="..." shareVolsizelimit="" shareExportNFS="-" shareExportNFSFsid="0" shareSecurityNFS="public" shareHostListNFS="" # Share exists on corsair2ssd,corsair1ssd Share exists on corsair2ssd,corsair1ssd. That is strange. Edited March 11, 2022 by widdefmh Quote Link to comment

JorgeB Posted March 11, 2022 Share Posted March 11, 2022 Like suspected both devices are in the same pool, easiest way to fix is by doing the below, since I don't know which Unraid version you're using make sure you don't change the number of cache slots when removing the pool device, there's a bug in some releases. -stop the array -unassign both pool devices -start array -stop array -assign both devices to the same pool, to the one where you want the existing data, there can't be a "all data will be delete" warning in front of any member -start array -stop array -unassign the device you want to remove from that pool -start array -wait for the btrfs balance to finish, when it does stop the array -you can now assign the removed device to the other pool -start array, there will be an option to format that pool and once that's done you can use it.

Thanks a lot! (despite my unwillingness to share the complete diagnostic file ) I am running version 6.9.2 of Unraid. Just curious, how did they end up in the same pools? I have not defined them that way.. I have, from the very beginning put them in separate pools.. Edited March 11, 2022 by widdefmh Quote Link to comment

Only logical explanation is that a some point in the past they were both assigned to the same pool, but would need the syslog to confirm, if the server didn't reboot since it happened.

widdefmh Posted March 11, 2022 Author Share Posted March 11, 2022 (edited) And the thing about not changing the numer of cache slots. Both cache slots are set to 1, so I really have to change it in order to put both in the same pool... I did set up the pools long time ago and the server has been rebooted several times since then. This is really weird because I can not recall that I have put them in the same pool. Can Unraid be confused if two identical discs is used? I saw they had the same UUID.. In this case two identical discs is used and it is only with those 2 cache pools I have problems.. I have more pools and they work just fine with no confusion..

JorgeB Posted March 11, 2022 Share Posted March 11, 2022 but v6.9.2 is not affected by the bug and won't let you anyway, so it's fine. Quote Link to comment

widdefmh Posted March 11, 2022 Author Share Posted March 11, 2022 (edited) Well, did this not go as I wanted. I could not add both devices to the same pool without increase the slots to 2. Now I can not remove the disc I added to the pool. Can not restart the array when removing one of the discs. I changed the share appdata to another disc and ran mover.. But nothing happens.. How can I move all appdata (docker containers) to another disc so I don't loose everything on the disc pool? Will remove the cache pools and start over, but I have to move the data in the pool... Edited March 11, 2022 by widdefmh Quote Link to comment
trurl Posted March 11, 2022 Share Posted March 11, 2022 Mover only moves files from the designated pool to the array for cache-yes share, or from the array to the designated pool for cache-prefer shares. Mover ignores cache-only and cache-no shares, and it doesn't move files between array disks or between pools. Also, nothing can move or delete open files, so you have to disable Docker in Settings. If you want more detailed advice based on your specific configuration post diagnostics. Quote Link to comment
widdefmh Posted March 11, 2022 Author Share Posted March 11, 2022 (edited) Well, I removed the other 2 pools and created a completely new pool with a new name.. I ONLY added one of the crucial ssd discs to the new pool. The number of slots were set to 1. When running btrfs fi usage -T /mnt/crucialmx500ssd I get the following result AGAIN: btrfs fi usage -T /mnt/crucialmx500ssd Overall: Device size: 1.82TiB Device allocated: 6.06GiB Device unallocated: 1.81TiB Device missing: 0.00B Used: 2.38GiB Free (estimated): 929.32GiB (min: 929.32GiB) Free (statfs, df): 929.32GiB Data ratio: 2.00 Metadata ratio: 2.00 Global reserve: 3.25MiB (used: 0.00B) Multiple profiles: no Data Metadata System Id Path RAID1 RAID1 RAID1 Unallocated -- --------- ------- -------- -------- ----------- 1 /dev/sdb1 2.00GiB 1.00GiB 32.00MiB 928.48GiB 2 /dev/sdc1 2.00GiB 1.00GiB 32.00MiB 928.48GiB -- --------- ------- -------- -------- ----------- Total 2.00GiB 1.00GiB 32.00MiB 1.81TiB Used 1.16GiB 31.78MiB 16.00KiB This has to be a bug. Unraid adds both of my Crucial MX 500 discs to the pool even when the slot is only set to 1 and only 1 disc is selected. Now one of the drives is an unassigned device and I could even mount it as a unassigned device. It is still a part of the pool as stated above. Edited March 11, 2022 by widdefmh Quote Link to comment

Did you finish the balance operation to remove the drive? 4 hours ago, JorgeB said: -stop the array -unassign both pool devices -start array -stop array -assign both devices to the same pool, to the one where you want the existing data, there can't be a "all data will be delete" warning in front of any member -start array -stop array -unassign the device you want to remove from that pool -start array -wait for the btrfs balance to finish, when it does stop the array Until the BTRFS filesystem has purged the drive from the pool, it will remain linked no matter where you assign it or don't, as long as it's physically connected and recognized. If you don't mind losing the data on both devices you can run blkdiscard /dev/??? on both and they will no longer have the BTRFS pool data. Quote Link to comment

Just need to check the "I want to do this" or similar box next to the array start button. Quote Link to comment
