I am trying out the xfs_fsr utility, but am not having much luck getting it to
actually do anything. Running with -vd, I see a flood of 'no such file
messages' like the following.
ino=570425612 extents=12 can_save=11 tmp=/disk08-01/.fsr/ag329/tmp22898
could not open tmp file: /disk08-01/.fsr/ag329/tmp22898: No such file or
Just for the fun of it, I tried creating some of these directories, only to
find the operation bails in the ioctl.
ino=570425630 extents=13 can_save=12 tmp=/disk08-01/.fsr/ag328/tmp22898
DEBUG: fsize=445760 blsz_dio=445440 d_min=512 d_max=2147483136 pgsz=4096
Temporary file has 1 extents (13 in original)
XFS_IOC_SWAPEXT failed: ino=570425630: Invalid argument
xfs_fsr is coming from xfsprogs 3.0.0
Linux kernel is 18.104.22.168
Architecture is x86_64, but xfs_fsr is 32bit.
I did some searching for through past post for any similiar cases, but could
not find any. Here are some other useful outputs that I found from somewhat
# xfs_db -c frag -f /dev/sdp2
actual 38348, ideal 1318, fragmentation factor 96.56%
Most of the files appear to have single extent layouts, but there are a few
# xfs_db -c "frag -v" -f /dev/sdp2
inode 570425622 actual 957 ideal 1
I did a quick check of the 'bmap' of the inode listed above and the file looks
non-sparse (all 'flag 0')
