Hello,
I have a 4 disk raid 5 array which I can't reassmble after one drive in the array failed and caused the port-multiplier to reset multiple times which messed up the array.
Is there any way to get the other 3 drives back in sync to re-assemble the array?
Thanks,
Andrew
/dev/sdd1 and /dev/sde1 are both good. /dev/sdh1 is good but won't re-add. /dev/sdi1 is the failing drive.
