--- Comment #18 from Richard Ems
The RAID system probably also changed, we were adding disks to the shelf, now it's full with 24 x 1 TB Hitachi HDDs. and how does the raid setup look like?
The backup system is a RAID 6 array, with 23 x 1 TB HDDs, 1 HDD is set as hot spare. XFS filesystem on it.
so, it`s likely that there were changes to mptscsi and i (for myself) would try downgrading the kernel to see if it makes a difference.
This is a production system. Perhaps I can downgrade next weekend, but this depends on our production load.
anyway - you have lsi scsi controller AND areca raid controller in your system -i assume you have the backup disks attached to the areca controller?
No no. Forget the Areca controller, it has nothing to do with this errors, at least nothing that *I* know of, it would be very weird if it does. The Infortrend system used for the backups is attached to the LSI SCSI controller. On the Areca controller we have also a RAID 6 array, mounted at /home . But all the errors come from the mptscsih driver, nothing from the arcmsr driver.
how is areca raid controller related to mptscsih? doesn`t that belong to the lsi controller?
not sure, but maybe it would be useful if you would describe your disk/raid/partition/device layout...!?
So here again: 1. openSUSE 11.1 64 bit, kernel 2.6.27.39-0.2-default, on local RAID 1, 2 x 160 GB HDDs. Everything running fine here. 2. one external HDD shelf, mounted at /home, attached to the Areca 1680 controller, with one RAID 6 array on 11 x 1 TB Seagate SAS HDDs. 3. one external Infortrend A24U-G2421 system for backups, attached to the LSI SCSI controller, with one RAID 6 array on 23 x 1 TB Hitachi SATA HDDs, XFS filesystem. Here is where we are having the freezes. c3m:~ # cat /proc/partitions major minor #blocks name 8 0 20506407936 sda 8 1 20506407902 sda1 8 16 12695308288 sdb 8 17 12695308254 sdb1 8 32 156249856 sdc 8 33 10490413 sdc1 8 34 2104515 sdc2 8 35 143653230 sdc3 253 0 41943040 dm-0 253 1 52428800 dm-1 253 2 10485760 dm-2 253 3 10485760 dm-3 253 4 10485760 dm-4 253 5 10485760 dm-5 c3m:~ # cat /etc/fstab /dev/disk/by-id/scsi-20004d927fffff800-part1 / ext3 acl,user_xattr 1 1 /dev/disk/by-id/dm-name-vg1-opt /opt ext3 acl,user_xattr 1 2 /dev/disk/by-id/dm-name-vg1-srv /srv ext3 acl,user_xattr 1 2 /dev/disk/by-id/dm-name-vg1-tmp /tmp ext3 acl,user_xattr 1 2 /dev/disk/by-id/dm-name-vg1-usr /usr ext3 acl,user_xattr 1 2 /dev/disk/by-id/dm-name-vg1-software /usr/local/software ext3 acl,user_xattr 1 2 /dev/disk/by-id/dm-name-vg1-var /var ext3 acl,user_xattr 1 2 ### /dev/disk/by-id/scsi-20004d927fffff802-part1 /home-old xfs defaults,ro 1 2 LABEL=home2 /home xfs defaults 1 2 ### /dev/disk/by-id/scsi-20004d927fffff800-part2 swap swap defaults 0 0 proc /proc proc defaults 0 0 sysfs /sys sysfs noauto 0 0 debugfs /sys/kernel/debug debugfs noauto 0 0 usbfs /proc/bus/usb usbfs noauto 0 0 devpts /dev/pts devpts mode=0620,gid=5 0 0 /dev/disk/by-id/scsi-3600d02300070a9c30ffb202f83b35100-part1 /backup/IFT xfs defaults,rw 0 0 /backup/IFT /backup/IFT auto bind /backup/IFT /backup/IFT auto bind,remount,ro /dev/disk/by-id/usb-LaCie_BiggerDisk_AABF04D7133B-0:0-part1 /backup/LaCie-disc-1 xfs noauto 0 0 /dev/disk/by-id/usb-LaCie_BiggerDisk_AABF04D40115-0:0-part1 /backup/LaCie-disc-2 xfs noauto 0 0 c3m:~ # df -hl Filesystem Size Used Avail Use% Mounted on /dev/sdc1 9.9G 732M 8.7G 8% / udev 2.0G 140K 2.0G 1% /dev /dev/dm-0 40G 27G 12G 70% /opt /dev/dm-2 9.9G 184M 9.2G 2% /srv /dev/dm-3 9.9G 161M 9.2G 2% /tmp /dev/dm-4 9.9G 5.8G 3.7G 62% /usr /dev/dm-1 50G 38G 13G 76% /usr/local/software /dev/dm-5 9.9G 1.1G 8.3G 12% /var /dev/sdb1 12T 11T 1.7T 87% /home /dev/sda1 20T 18T 1.5T 93% /backup/IFT This is it.
