I'm not sure if they mean they increased the size of the FS while it was scrubbing. Definitely not a good idea, IMO. It is probably significant that over the last year, I see a fair number of issues with crashes and unrecoverable data on the btrfs list. I've been using Btrfs for several years. It works quite well. I chose it over ZFS for its flexibility. The only issues I had are mostly my idiocy. Thankfully I was able to recover and didn't lose any data. Just a data point ;) On the ZFS list, most of the discussion is about optimal configurations. -dsr- An update about the scrub: an hour or so later the percentage went back to 1%. I don't remember what happened to the other parameters, but I just cancelled it anyway. I didn't have any errors, thankfully, as usual.

Btrfs scrub going past 100%
Hello, I run regular btrfs scrubs through btrfsmaintenance on my disk array without issues. This time, though, the scrub percentage went over 100%. I kept it running so that I can file a bug if this is one. Which package do I file this against? I believe it's in the Linux kernel not btrfs-progs, but I thought I would ask since I'm new to this. Below is the scrub status:- user@pc ] sudo btrfs scrub status /mnt/SA1/ UUID: ---- Scrub started: Thu Jul 1 00:03:28 2021 Status: running Duration: 35:08:10 Time left: 0:38:00 ETA: Fri Jul 2 11:49:38 2021 Total to scrub: 29.07TiB Bytes scrubbed: 28.56TiB (98.23%) Rate: 236.75MiB/s Error summary: no errors found user@pc ] sudo btrfs scrub status /mnt/SA1/ UUID: ---- Scrub started: Thu Jul 1 00:03:28 2021 Status: running Duration: 37:13:49 Time left: 21358913:01:19 ETA: Mon Feb 11 06:18:36 4458 Total to scrub: 29.08TiB Bytes scrubbed: 29.24TiB (100.56%) Rate: 228.79MiB/s Error summary: no errors found Thanks
