Upgrading to v10. RAID. Or RANSID.

So, lots of you will be wanting to move your SME to new hardware as part of your upgrade.

Before you go racing into buying your new Redundant Array of Inexpensive Drives (and to those of you who have already done so) you really need to read this article.

https://raid.wiki.kernel.org/index.php/Timeout_Mismatch

Read some of the links on SMR drives as well.

In essence a number of hard drive manufacturers have slipped out new technology into hard drives which means that they can fail on a RAID rebuild. Particularly of concern are WD Red NAS drives - notably the 3.5" 2-6Tb (and may be larger) - which are the drive of choice for many.

Check these. If yours is SMR it is NOT suitable for RAID at ALL. You can RMA an existing drive. I would, fast.

Note, removing and rebuilding will then stress the other drives. You are going to need some VERY careful planning to migrate this. Make sure you have LOTS of backups.

The side effect of this is I have a new acronym for you now.

Redundant Array of Not So Inexpensive Drives

"RANSID"

:lol:
...
1. Read the Manual
2. Read the Wiki
3. Don't ask for support on Unsupported versions of software
4. I have a job, wife, and kids and do this in my spare time. If you want something fixed, please help.
