NAME¶

SYNOPSIS¶

DESCRIPTION¶

Ever deleted too many subvolumes at the same time, resulting in having a kernel thread "btrfs-cleaner" go wild using cpu or writing to disk? There's no way to stop this process any more, but at least we can get a good idea what progress it is making.

Because the needed information is retrieved using the btrfs kernel API, it has to be run as root.

btrfs-orphan-cleaner-progress shows the amount of orphaned subvolumes that are waiting to be removed. If current one that is being processed takes more than a fraction of time, progress will be reported with 2 minute intervals.

Example output:
