Thanks for that reply, Jason.
I just looked at the man page for xfs_fsr. It's
a bit sketchy -- it doesn't really give good examples of what kinds of
files it would be appropriate to use this on.
For instance, I am storing
thousands of fairly large video and audio files -- in general, they may be
anywhere from 10s of MBs up to 2 GBs in size. After many months and
cyles of creating such files and deleting such files, maybe it will be
a good idea to run xfs_fsr (I imagine that the best time to run it would be
when many files have just been deleted, and as few files as possible
remain on a file system).
Questions:
1) Does xfs_fsr reorganize "free space"?
2) How safe is xfs_fsr? Is there any risk in running it?
3) How large a benefit can be gained from running it?
4) Is there any utility to visually see how fragmented an xfs
filesystem is?
It was/is my understanding that xfs suffers far less from fragmentation
than many other filesystems (such as NTFS). Can you explain why that
is? And, once again, how can you know when fragmentation is becoming
and issue (other than "guessing" that you're seeing lowered performance)?
Hope to hear fro you and others soon.
Happy Holidays,
Andy Liebman
