Mark,
I might know a little bit more about what's causing this particular panic. I'm
currently running OpenSolaris as a guest OS under VMware Server RC1 on a CentOS
4.3 host OS. I have 3 - 300GB (~280GB usable) SATA disks in the server that
are all formatted under CentOS like so:
[EMAIL PROTECTED] sdb]# fdisk -l /dev/sda
Disk /dev/sda: 300.0 GB, 300069052416 bytes
255 heads, 63 sectors/track, 36481 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 * 1 3187 25599546 fd Linux raid autodetect
/dev/sda2 3188 36481 267434055 bf Solaris[/b]
So I use the first ~25GB/disk in a Linux software RAID 5, the rest of the disk
~240GB (usable) is given to OpenSolaris (via VMware) as a raw physical disk
partition. OpenSolaris still thinks that those disks that it's been given are
the full size (~280GB) -- PROBLEM 1.
Next I can create a simple ZFS pool using one of the SATA disks like so:
[b]bash-3.00# zpool create sata c2t0d0[/b]
Then I copy an iso file from my OpenBSD file server via ftp... As soon as data
starts writing into the ZFS file system I notice zpool CKSUM errors -- PROBLEM
2. The first time I saw this problem occur I never checked the output of zpool
status, and I believe I must have had a bunch of CKSUM errors then too.
Current info:
[b]bash-3.00# pwd
/data
bash-3.00# ls -al
total 1423398
drwxr-xr-x 2 root sys 3 Jun 15 20:55 .
drwxr-xr-x 43 root root 1024 Jun 15 20:57 ..
-rw-r--r-- 1 root root 728190976 Sep 23 2005
KNOPPIX_V4.0.2CD-2005-09-23-EN.iso
bash-3.00# zpool status
pool: sata
state: ONLINE
status: One or more devices has experienced an unrecoverable error. An
attempt was made to correct the error. Applications are unaffected.
action: Determine if the device needs to be replaced, and clear the errors
using 'zpool clear' or replace the device with 'zpool replace'.
see: http://www.sun.com/msg/ZFS-8000-9P
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
sata ONLINE 0 0 20
c2t0d0 ONLINE 0 0 20
errors: No known data errors
bash-3.00# zfs list
NAME USED AVAIL REFER MOUNTPOINT
sata 695M 273G 24.5K /sata
sata/data 695M 273G 695M /data
sata/mp3s 24.5K 273G 24.5K /mp3s[/b]
Now, I attempt to mount the iso file via lofiadm and the panic occurs:
[b]bash-3.00# mount -F hsfs `lofiadm -a
/data/KNOPPIX_V4.0.2CD-2005-09-23-EN.iso` /tmp/test[/b]
I have also tested the above scenario but instead of giving OpenSolaris the
SATA disk via raw physical disk access I create a VMware vmdk disk image file
on the SATA disk and give that to OpenSolaris. In this case I can successfully
create a ZFS file system, copy the same iso to it, and mount it via lofiadm.
So I have a new panic/crash dump -- it's absolutely huge, ~400MB after tar and
bzip. If you still want it I can upload it to sunsolve as you requested. Or
if there is a way to make it smaller let me know.
Thanks,
Nate
