Subject: [PATCH 0/6] Support resize and device delete cancel ops
Date: Fri, 21 May 2021 14:06:24 +0200 [thread overview]
Message-ID: <cover.1621526221.git.dsterba@suse.com> (raw)
We don't have a nice interface to cancel the resize or device deletion
from a command. Since recently, both commands can be interrupted by a
signal, which also means Ctrl-C from terminal, but given the long
history of absence of the commands I think this is not yet well known.
Examples:
$ btrfs fi resize -10G /mnt
...
$ btrfs fi resize cancel /mnt
$ btrfs device delete /dev/sdx /mnt
...
$ btrfs device delete cancel /mnt
The cancel request returns once the resize/delete command finishes
processing of the currently relocated chunk. The btrfs-progs needs to be
updated as well to skip checks of the sysfs exclusive_operation file
added in 5.10 (raw ioctl would work).
David Sterba (6):
btrfs: protect exclusive_operation by super_lock
btrfs: add cancelable chunk relocation support
btrfs: introduce try-lock semantics for exclusive op start
btrfs: add wrapper for conditional start of exclusive operation
btrfs: add cancelation to resize
btrfs: add device delete cancel
