 |
|
Hi,
I have problems with a raid 6 created with 24x1TB disks on an Adaptec 52445. I don't know if this is the correct place to ask this. I hope it is not very wrong...
Description of the problem:
One day I got IO errors when reading and writing data from the partition where the raid is.
I unmounted the partition where the raid was, made some checks and detected that one disk was having problems (#19). I switched off the system and changed the faulty disk. Then I expected to have access to the raid again, but this was not the case: the raid went offline; doing "arcconf GETCONFIG 1 al" (arcconf is the command line utility that adaptec provides) gives:

As you can see both disk #19 and #23 are ready instead of online. Why ready and not online? Why #23, if it seems to be okay when I run the checks on it?
What can I do to recover the data on the raid? Should I force the raid to an online status?
Is any expert there who can help me?
Thanks in advance.
