In your position, I would just go ahead and delete the RAID 5, swap both drives, lay down a new virtual disk, reinstall, and recover from a file level backup. It'll be a pain in the butt, but it will leave you covered from any replication of bad data blocks causing storage problems. However, if you export a RAID log and it looks like there aren't any errors on the foreign drive, importing and rebuilding will be fine. Provided that disk 0 was the only one with errors, you could very well be fine. But if there are errors on drive 2 as well, those will replicate on the first rebuild and swapping out that drive would migrate those bad blocks back when the rebuild starts. If there is any volume of bad blocks, then reading and writing all of them may lead to drive failures. The best way to proceed really depends on what you see in the PERC log. However, the safest option is the one I listed on top.
Hi I'm new to here Have a raid 5 virtual device offline, in VD Mgmt when I check properties of my virtual device. It show 4 physical disks and 2 missing disks. Then I switch to PD Mgmg page, it shows 4 online physical disks with state online (Driver 01, 03, 04, 05) and 1 with state foreign (driver 02). I checked my iDRAC and server found a record "Fault detected on Drive 0". I assume one of the two missing disk is Drive 0, but why my Drive 2 state changed to foreign? (Checked server, driver 0 led is off and other is on) Is there any solution to get my raid 5 back to online? (have a spare disk without installed) Thanks in advance Update: After import driver 2. I was able to boot the system and backup all hyper-v vm data
