Subject: suddenly slow writes on XFS Filesystem
Date: Sun, 06 May 2012 11:01:14 +0200 [thread overview]
Message-ID: <4FA63DDA.9070707@profihost.ag> (raw)
Hi,
since a few days i've experienced a really slow fs on one of our backup
systems.
I'm not sure whether this is XFS related or related to the Controller /
Disks.
It is a raid 10 of 20 SATA Disks and i can only write to them with about
700kb/s while doing random i/o. I tried vanilla Kernel 3.0.30 and 3.3.4
- no difference. Writing to another partition on another xfs array works
fine.
Details:
#~ df -h
/dev/sdb1 4,6T 4,4T 207G 96% /mnt
#~ df -i
/dev/sdb1 4875737052 4659318044 216419008 96% /mnt
#~ xfs_db -c frag -r /dev/sdb1
actual 83160469, ideal 82145389, fragmentation factor 1,22%
#~ xfs_info /dev/sdb1

Any ideas?
Stefan
