Greetings all --
I'm running FreeBSD 6.1-RELEASE on i386 with a stock kernel, and am
trying to build a 4 disk RAID5 array using vinum. The issue is that,
once the system is rebooted after initially creating the array, the
subdisks come up as stale.
I first started by creating a 4 subdisk array on the 4 devices, with
each subdisk sized at 200GB. This configuration I used to test
performance and verify the disk subsystem. I used UFS2 with 64K
blocks and 8K fragments.
I then deleted the volume, plex, and subdisks in order to do some
performance testing on one of the drives using an fdisk-style
partition with a UFS2 filesystem. This filesystem was created using
the same block/fragment settings. I ran bonnie++ on this filesystem
and did some bulk copies to check on performance.
I then returned to gvinum to recreate my RAID5 array. The
configuration file I used was similar to, but not exactly the same as
the original configuration file as I wanted to try a different stripe
size. The filesystem was created with the same configuration as listed above.
After running gvinum create gvinum.config, formatting the filesystem,
and mounting it, I am able to successfully use the filesystem to read
and write data. However, after rebooting, the subdisks all show as
being stale, as shown below:
gvinum -> list
4 drives:
D drive03 State: up /dev/ad4 A:
38474/238475 MB (16%)
D drive02 State: up /dev/ad6 A:
38474/238475 MB (16%)
D drive04 State: up /dev/ad8 A:
38474/238475 MB (16%)
D drive01 State: up /dev/ad10 A:
38474/238475 MB (16%)
1 volume:
V vol1 State: down Plexes: 1 Size: 585 GB
1 plex:
P vol1.p0 R5 State: down Subdisks: 4 Size: 585 GB
4 subdisks:
S vol1.p0.s0 State: stale D: drive01 Size: 195 GB
S vol1.p0.s1 State: stale D: drive02 Size: 195 GB
S vol1.p0.s2 State: stale D: drive03 Size: 195 GB
S vol1.p0.s3 State: stale D: drive04 Size: 195 GB
gvinum -> quit
There is not a /var/log/vinum_history file. grep vinum
/var/log/messages yielded the one line below:
Aug 16 23:36:08 archive kernel:
g_vfs_done():gvinum/vol1[READ(offset=65536, length=8192)]error = 6
Thanks in advance for any suggestions you might have.
Steve
