Hi!
I wanted to consult my situation before performing the upgrade. My aim is to upgrade both parity and one data drive - upgrading my 6TBs to 12TBs. I`m scared of data loss or any other crap that might happen during the upgrade and honestly, I`m not confident with just replacing the parity drive, let it sync and then do the same with data drive (because my server uses just 1 parity drive).
Therefore, all I wanted to consult is this procedure:
- upgrade/update everything in the server so it runs the latest SW
- disable all planned activities (mover, parity checks, backups)
- disable autostart of the array & docker/VMs
- perform flash backup
- start array in maintance mode & let it sync the parity
- unmount SSD cache disk (assigned in cache pool) and pull out completely
- mount the new 12TB drive instead of cache and make it 2nd parity drive
- let the new parity drive sync
- pull out old data drive & put in new 12TB new one
- let the server rebuild the data drive
- pull out 1st old parity drive (6TB one)
- put in cache drive to the original slot
- rewind all the changed settings
- live happily ever after
Summary:
- old state: 1 parity (6TB) + 4 x data (6TB) + 1 SSD cache
- new state: 1 parity (12Tb) + 3 x data (6tb) + 1 x data (12TB) + 1 SSD cache)
Is this procedure safe & and actually doable? Have I forgotten anything which should be definitely done?
PS: My MB offers 6 SATA ports, all of which are used. I wouldn`t be asking if I had large server with all the SATA slots I needed.
Thx a lot for the response! (I`m getting gray hair and haven`t even started )
