Subject: irregular mkfs.xfs results on identical HW
Date: Thu, 25 Sep 2014 22:01:08 +0200 [thread overview]
Message-ID: <54247484.2030808@physik.uni-freiburg.de> (raw)

Dear all,
servers with identical disk setup (HW RAID0 H310a):
Disk /dev/sda: 598.9 GB, 598879502336 bytes
/dev/sda1 1 49152 394813439+ 82 Linux swap / Solaris
/dev/sda2 49153 50176 8225280 83 Linux
/dev/sda3 6399 72809 533446357+ 44 Unknown
mkfs.xfs creates on 28 of them:
meta-data=/dev/sda3 isize=256 agcount=16, agsize=8335099 blks
= sectsz=512 attr=1, projid32bit=0
data = bsize=4096 blocks=133361584, imaxpct=25
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0
log =internal bsize=4096 blocks=32768, version=1
= sectsz=512 sunit=0 blks, lazy-count=1
realtime =none extsz=4096 blocks=0, rtextents=0
but on four out of them:
meta-data=/dev/sda3 isize=256 agcount=4, agsize=33340398 blks
= sectsz=512 attr=2, projid32bit=0
data = bsize=4096 blocks=133361589, imaxpct=25
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0
log =internal bsize=4096 blocks=65117, version=2
= sectsz=512 sunit=0 blks, lazy-count=1
realtime =none extsz=4096 blocks=0, rtextents=0
I did not find a way to add mkfs.xfs options to get the identical
filesystem setup on all nodes, e.g.
# mkfs.xfs -d agcount=16 -b size=4096 /dev/sda3 -f
meta-data=/dev/sda3 isize=256 agcount=16, agsize=8335100 blks
= sectsz=512 attr=2, projid32bit=0
data = bsize=4096 blocks=133361589, imaxpct=25
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0
log =internal log bsize=4096 blocks=65117, version=2
= sectsz=512 sunit=0 blks, lazy-count=1
realtime =none extsz=4096 blocks=0, rtextents=0
The only way it worked was to dump nodeA:/dev/sda3 to nodeB:/dev/sda3
Is there an explanation? May be I missed something ... hints?
Cheers and thanks in advance
Anton
