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? - -- VH -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iFYEAREIAAYFAkkFlRsACgkQhQBMvHf/WHn6fQDbBv7gpSV3x2GwDsM5VeVI+iax oCp7aGDcgFwD9ADaAzA219KdJfu2aCgZfqXOthqvJhah6u06VObcIw== =jm7d -----END PGP SIGNATURE-----
