Thread: Raid 1 failures

-

i'm running ubuntu 11.10 main boot partition , s/w on ssd , raid 1 partition setup holding mythtv recordings. server set auto-start when there recording made. problem (and sometimes) system doesn't boot stops @ point requests os use (no when there's no 1 around!!) hitting return on default ubuntu version selected results in system completing startup. past investigations suggested failure due raid 1 partition not coming up, i've seen, example, situation array has 1 disc , needs other recovered (which being 1tb can take time), re-boot can resolve straight away. system not starting seems random , seems related raid 1 array failing start. think i've seen mentioned known problem linux raid, however, ideas might causing problem and/or how fix welcome i'd system become operational 1 replacing ageing 8.10 mythtv system, @ moment can't happen it's unreliable.

check cables. had similar issue , loose sata cable. vibration fans in array loosened connection on time. ended switching 90 deg sata cables , issue solved. 5+ yrs ago. no problem since.

also, i'd suggest migrating 12.04 - lts supported release. if other machines connect internet @ all, there risk of being hacked on non-maintained releases. know already, i'm certain.
