luigi408 Posted February 4, 2017 Share Posted February 4, 2017 Hi all, I updated to the latest Unraid. After reboot I got this message on me email regarding a warning from my server: Event: unRAID Cache disk message Subject: Warning [HOMESERVER] - Cache pool BTRFS too many profiles Description: Crucial_CT250MX200SSD1_162513059F49 (sdd) Importance: warning Can anyone explain to me what this means and how I can fix it? Thank you very much. Link to comment
JorgeB Posted February 4, 2017 Share Posted February 4, 2017 That means that there's more then a data profile in use, most common on earlier btrfs kernels and usually easily fixable, post the output of: btrfs fi df /mnt/cache Link to comment
limetech Posted February 4, 2017 Share Posted February 4, 2017 Also, what version of unRAID OS did you upgrade from? Link to comment
clevoir Posted February 4, 2017 Share Posted February 4, 2017 I am having the same problem and updated from 6.2.4 Output is Data, RAID1: total=109.00Gib, used=106.62GiB Data, single: total=1.00GiB, used=0.00B System, RAID: total=32.00MiB, used=16.00KiB Metadata, RAID1: total=2.00GiB, used=257.89MiB GlobalReserve, single: total=16.58MiB, used=0.00B Link to comment
JorgeB Posted February 4, 2017 Share Posted February 4, 2017 Single profile is unused but a balance will get rid of it, on the main page click on cache and then on balance using the default options, check the output of fi df again in the end and raid1 data profile should be the only remaining one.

luigi408 Posted February 4, 2017 Author Share Posted February 4, 2017 I also upgraded from 6.2.4 (the last stable release). I had the same output as above. I ran that balance as suggested and I only have RAID1 showing. Thanks. Link to comment
clevoir Posted February 4, 2017 Share Posted February 4, 2017 I have run the balance command and this is now the output Data, RAID1: total=108.00GiB, used=106.61GiB System, RAID1: total=32.00MiB, used=16.00KiB Metadata, RAID1: total=1.00GiB, used=255.61MiB GlobalReserve, single: total=16.00MiB, used=0.00B Link to comment
kyis Posted February 5, 2017 Share Posted February 5, 2017 I confirm this works: btrfs fi df /mnt/cache Data, RAID1: total=101.00GiB, used=98.05GiB System, RAID1: total=32.00MiB, used=16.00KiB Metadata, RAID1: total=1.00GiB, used=64.62MiB GlobalReserve, single: total=16.00MiB, used=0.00B Thanks!

levster Posted September 6, 2018 Share Posted September 6, 2018 I just added a second cache disk and am getting the same Cache pool BTRFS too many profiles message. Here are the outputs before and after the re-balance: before: Data, RAID1: total=172.00GiB, used=140.41GiB System, RAID1: total=32.00MiB, used=48.00KiB Metadata, RAID1: total=1.00GiB, used=306.72MiB GlobalReserve, single: total=28.53MiB, used=0.00B and after: Data, RAID1: total=141.00GiB, used=140.41GiB System, RAID1: total=32.00MiB, used=48.00KiB Metadata, RAID1: total=1.00GiB, used=307.00MiB GlobalReserve, single: total=28.77MiB, used=128.00KiB I still see the message displayed. Should I reboot for it to go away or do something else? Link to comment
JorgeB Posted September 6, 2018 Share Posted September 6, 2018 The message appears during the balance, it's normal, pool is fine now. Link to comment
levster Posted September 6, 2018 Share Posted September 6, 2018 I rebooted and the message went away. Thank you. Link to comment
JorgeB Posted September 7, 2018 Share Posted September 7, 2018 @bonienlwas thinking it might be a good idea to remove this notification, btrfs has fixed for while now the issue that resulted in multiple profiles, most users getting this will be during a cache upgrade/downgrade or profile change. Another option would be add something like "this warning is normal during a cache pool balance while the profile is being changed" Link to comment
bonienl Posted September 7, 2018 Share Posted September 7, 2018 Is it okay to add "You can ignore this warning when a cache pool balance operation is in progress" ? Ps. adding text is a lot easier than changing the code .... Link to comment
JorgeB Posted September 7, 2018 Share Posted September 7, 2018 Yep that's fine, thanks Link to comment
