ot: 3ware raid
wanted to give an update to anyone who was participating
in those raid controller threads a few days ago ..
seems 3ware has another hardware related issue which i
experienced first hand today.
i planned on comming into work around 12 or 1..but got
paged at 10:23 saying 2 of the services were down on
my backup server(3ware raid), so i tried to ssh to it..
nothin..went to the office and saw it had kernel panic'd.
reiserfs said buffer write failed and i saw a bunch of
SCSI DISK: I/O errors with sectors. rebooted the system
and the 3ware controller had marked one of my maxtor 80GB
drives offline.
contacted my vendor and they said that 3ware's controllers
cannot handle bad blocks as reported from the IDE drives.
if they encounter one it causes big problems(unlike a normal
ide controller which just waits while the drive re maps it).
i hooked the maxtor to the onboard intel controller and
ran the diagnostics, drive checked out as being in
perfect working order..re hooked it to the 3ware and
re initialized the raid array(didn't lose any data,
its just re integrating the drive into the raid10 array)
and the system is fine again for now ...the vendor said
3ware is comming out with updated firmware to solve the
issue. 3ware gave me a new unreleased driver today which
they said will help with the problem but im havin
trouble compilin the driver, waiting to hear back from
their support team.
so while they have decent quality drivers ....the
hardware has many issues! amazing it has this many
issues with the cards being available for so long.
im very happy with their responsiveness though.
even after today i would still choose 3ware over
adaptec and promise raid controllers on the sole
issue of better support. tho its sad that ive
had more problems with the controller then without..
