Hi,
I have a filesystem that (I think) is so full I cannot mount it. when I
do, it seems stuck in btrfs_start_pre_rw_mount->btrfs_orphan_cleanup
forever. I have let it run for a few hours, and it seems to be
incrementally reading/writing the filesystem, but I'm not sure if that's
a good thing or a bad thing. Below is a kernel stack of mount when
this is happening. I'm running btrfs check right now, and it's still on
step 4/7 but I'm committed to letting it finish this time, so I can be
sure that there's no underlying issues.
I've tried to mount clear_cache which seemed to run, but it didn't hange
that i'm stuck in orphan_cleanup. There are no btrfs error messages in
journald.
I'd like to get back to normal, my backups a bit old, so even a
read-only mount would be nice (I haven't yet tried) but I'm hopefully
for a resolution where I can just mount the thing, and free up a bunch
of space. My next great idea is just adding another disk to the
filesystem, but i thought it's time to ask for guidance from the list.
this filesystem is -d single -m raid1 and uses space group v2, which was
great because it use to take 5 minutes to mount the filesystem.
any guidance would be most appreciated, I've tried to include a cursory
detail of what's happening below. please let me know if there's
anything more I can provide or steps I should take.

Hi,
I have a filesystem that (I think) is so full I cannot mount it. when
I do, it seems stuck in btrfs_start_pre_rw_mount->btrfs_orphan_cleanup
forever. I have let it run for a few hours, and it seems to be
incrementally reading/writing the filesystem, but I'm not sure if
that's a good thing or a bad thing. Below is a kernel stack of mount
when this is happening. I'm running btrfs check right now, and it's
still on step 4/7 but I'm committed to letting it finish this time, so
I can be sure that there's no underlying issues.
I've tried to mount clear_cache which seemed to run, but it didn't
hange that I'm stuck in orphan_cleanup. There are no btrfs error
messages in journald.
I'd like to get back to normal, my backups are a bit old, so even a
read-only mount would be nice (I haven't yet tried) but I'm hoping for
a resolution where I can just mount the thing, and free up a bunch of
space. My next great idea is just adding another disk to the
filesystem, but I thought it's time to ask for guidance from the list.
this filesystem is -d single -m raid1 and uses space group v2, which
was great because it used to take 5 minutes to mount the filesystem.
Any guidance would be most appreciated, I've tried to include a
cursory detail of what's happening below. Please let me know if
there's anything more I can provide or steps I should take.
