HDD becomes read only
Posted on 2014-01-14
We have some servers hosted by Peer1, and those servers hold our web-based database program.
Yesterday, one of the servers went down. They were able to bring it back up in about 2hours, but this disrupted our operation severely.
When asked for the cause, this is the explanation I got.
" The system went into read only. This doesn't appear to be from the RAID array but most likely a system error that protected you file system. Its best that you have the RAID one and this can prevent a drive failing and loosing the data on the server.
The following is the output from the system and the drive hours are not brand new but they are acceptable and I am confident in the hardware on your solution.
Power_On_Hours 0x0032 089 089 000 Old_age Always - 8124
Power_On_Hours 0x0032 082 082 000 Old_age Always - 13388
u0 RAID-1 OK - - - 232.82 Ri ON
p0 OK u0 233.81 GB SATA 0 - WDC WD2503ABYX-01WE
p1 OK u0 233.81 GB SATA 1 - WDC WD2503ABYX-01WE "
I don't understand why we even bother to have RAIDs if this could happen.
These servers are supposed to have brand new HDDs.
Is this something that could happen regularly, and how can we prepare for it?
