Checking filesystem on /dev/mapper/dshelf1
UUID: 36f5079e-ca6c-4855-8639-ccb82695c18d
checking extents
This causes a bunch of these:
btrfs-transacti: page allocation stalls for 23508ms, order:0,
mode:0x1400840(GFP_NOFS|__GFP_NOFAIL), nodemask=(null)
btrfs-transacti cpuset=/ mems_allowed=0
What's the recommended way out of this and which code is at fault? I can't tell
if btrfs is doing memory allocations wrong, or if it's just being undermined by
the block layer dying underneath.
And sadly, I'm also getting workqueues stalls like these:
