Hello all.
I'm very new to storage/RAID/etc.
I have a machine with (4) 3 TB drives in a RAID 5 configuration attached to an LSI RAID card. A few months ago I had a failed drive in the array so I replaced it. Unfortunately I experienced the "write hole" phenomenon during rebuild. At one point the machine froze up during rebuild and I had to hard reset it, I think this was where everything went wrong. And and I had to wipe the entire array, slow initialize it again, reinstall the OS. Needless to say it was a big pain.
Now, there is another failed drive in the array and I am really afraid of this happening again. Is there anything I can do to prevent this from happening again during the rebuild?
As far as I understand it, the write hole occurs when there is mismatched parity data from a power failure/corrupt data. Do I just hope that the computer doesn't freeze up, is there any sort of check I can perform to make sure that the array will rebuild properly? Thanks
I have an LSI 9260-8i and (4) Seagate 3 TB SATA drives.
