Hi,
I'd like to ask the list if anyone else has been seeing panics on DU 3.2c
while running defragment. We have been able to generate these
panics twice here on two different machines. Each time 'defragment' running
on just one domain can cause the system to go nuts with the line:
ADVFS EXCEPTION
Module = 28, Line = 1646
panic (cpu 0):
syncing disks... done
(O/S = 3.2c, firmware = latest, disk revision = latest)
Naturally I've registered the problem with DEC but they seem unable to come
up with a solution as yet and inform me that we are the only people
experiencing this probelm. Is this true? Is anyone else out there seeing
crashes running defragment?
Here is the head of the stack trace:
1 panic(...)
2 advfs_sad(...)
3 release_dirty_pg(...)
4 lgr_writev_ftx(...)
5 log_donerec_nunpin(...)
The process in memory at the time was 'defragment'.
Also, as the domain that causes panics is built on LSM and the LSM volume
is built on one disk only (rz1) - so we tried to swap this disk (even though
uerf showed no SCSI errors) but the panics were still there when we tried
defragmenting the new disk. Our domains typically contain large files
(approx 1Gb in size).
Any ideas? Any me too's?
