when I am trying to delete large files on btrfs, it takes several minutes, and disk is completely locked during this time: other processes are locked on FS API calls.

This makes btrfs unusable on prod system. Anyone knows any workarounds?

Base on research I tried disabling quota, and using following mount options, but it doesn't help: rw,noatime,compress-force=zstd:1,ssd,discard=async,space_cache=v2,commit=120

Thank you!

  • This isn't completely on point for btrfs, so I'm writing it in a comment. I experienced a similar bottleneck with ext4 filesystems, and switching them to xfs removed the bottleneck. I believe there must be a btrfs config that will remove this bottleneck, but if you can't find one, give xfs a try for these filesystems.

  • If you need snapshots and error detection & correction and transparent compression and other "advanced fs features", try zfs instead of btrfs. Depending on your distro, you'll almost certainly have to install it yourself as a dkms module but that's a trivially easy operation and you end up with an advanced modern fs that actually works reliably.

  • I need transparent compression so xfs is not an options. I think I will need to move to zfs, but just hoped there is some easy fix for btrfs..

  • Likely workaround: you could maybe substitute the file removal with a series of truncate operations. (truncate command in shell). It would probably prevent the locking, although ugly.

  • I use some databases, and need to delete large tables, so its not up to me how files are deleted.
