The mount man page lists the ability to change the sunit and swidth via
mount options.
Is that the case? Does it work? I will Use The Source(tm) if no one
wants to answer. However, everyone keeps reiterating the complexity of
XFS, and maybe someon knows.
Here are my current mount options.
/dev/sda1 /snapshots xfs
noatime,nodiratime,logbufs=8,sunit=16,swidth=48 0 0
Here is xfs_info:
meta-data=/snapshots isize=256 agcount=32, agsize=4577708
blks
= sectsz=512
data = bsize=4096 blocks=146486656, imaxpct=25
= sunit=0 swidth=0 blks, unwritten=1
naming =version 2 bsize=4096
log =internal bsize=4096 blocks=32768, version=1
= sectsz=512 sunit=0 blks
realtime =none extsz=65536 blocks=0, rtextents=0
-----------
I don't see any change in sunit nor swidth. The previous admin did not
know about XFS options for arrays.
thanks,
Joshua
