Subject: Hard Disk problems
A few days ago I started getting some disk errors and can't
seem to find a
reference to find a way to fix them (other than the obvious re-format)
The daily security run output contains the following (abbreviated)
Checking setuid files and devices:
find: /usr/ports/databases/db43/work/db-4.3.28/db: Input/output error
find: /usr/ports/devel/git/Makefile: Input/output error
~ repeated 32 times for different files (thankfully all in
the ports tree)
tower.home.com kernel log messages:
ad0: FAILURE - READ_DMA status=51READY,DSC,ERROR
error=40UNCORRECTABLE LBA=139102367
ad0: FAILURE - READ_DMA status=51READY,DSC,ERROR
error=1ILLEGAL_LENGTH LBA=139102367
These 2 error codes are repeated a total of 38 times all with
the same LBA
If I start in single user mode and do fsck it takes about
half an hour to
get through and repeats similar errors many times for just
about every check
it does.
Running #fsck -y fsckout (while in multiuser mode) is as follows -
followed by dmesg output since boot
cat fsckout
