Hi,
I have recently bought a new disk (Seagate 500G, ST3500320NS). I have
enabled SMART checking using the smartmontools as usual for the disk
(/dev/ad6 -a -S on -s (S/../.././03|L/../../7/03) -m root). The problem
is that each time the test runs I get messages like the following in
/var/log/messages:
Oct 26 04:54:15 35 kernel: ad6: TIMEOUT - WRITE_DMA48 retrying (1 retry
left) LBA=836986454
Oct 26 04:54:25 35 kernel: ad6: TIMEOUT - WRITE_DMA48 retrying (0
retries left) LBA=836986454
Oct 26 04:54:25 35 kernel: ad6: FAILURE - WRITE_DMA48 timed out
LBA=836986454
Oct 26 04:54:25 35 kernel: g_vfs_done():ad6s2d[WRITE(offset=13150142464,
length=16384)]error = 5
And the SMART test results log on the disk contains line like this:
# 1 Short offline Interrupted (host reset) 00% 297
-
This is on 7.1-PRERELEASE #0: Wed Oct 15 18:56:54 UTC 2008, with GENERIC
kernel.
Now, does the timeout cause loss of any data? Is there anything besides
disabling the testing that I can do about it?
