Title: Upsizing HDD in Raid 1
Post by: morpheus on October 24, 2017, 08:57:27 AM
Following the directions here https://wiki.contribs.org/Raid#Replacing_and_Upgrading_Hard_Drive_after_HD_fail for upsizing disks in Raid 1 array. The original disks were 2TB but with business growth upgrading to 4TB.

The instructions say to wait until drives are synced. How do I tell they are synced and I can shutdown to go to the next step?

Could that not be put on that line in the wiki - especially for new users and occasional users like me?

Also Manage Disk Redundancy from the console menu

In the console manager where/how does it report sync status? I must have missed something - just reports that I only have 1 drive RAID and that I need to reboot ... which I did after waiting until no disk activity lights

When you have more than one drive in a Raid1 and they are syncing, can be a few reasons why, most obvious is replacing a drive, the sync progress will be displayed.

If you happen to have a system that was setup with just one drive and you install a second drive, the console Manage Disk Redundancy will offer you the opportunity to add the new drive to a Raid 1 and will begin to sync the drives..

You say you are informed in the console menu you have a 1 disk raid, I presume you originally had a at least two..

Added: sometimes a disk will be  kicked out of the Raid, it may require manual intervention, sometimes on a reboot you will be offered the chance to add it back from the console menu.

There are multiple references to what I have described in the wiki page you are following https://wiki.contribs.org/Raid

If you are actually following the link you provided, then it says:

 Login to the admin panel and manage raid to add new (larger) drive to system.
 Wait for raid to fully sync

By logging in to the admin panel (console) (which is NOT server manager), you will have a text style graphical display that shows onscreen the RAID1 sync process. Log in at the command line as admin to open this.
In that case there is no need to manually issue the commands I mentioned before.

Here is one example where you see the cat /proc/mdstat command

My question was (and remains) - where in the console manager (option 5) does it show sync status?

Well you have to select Manage drives & it should show you current status. Then when you choose to sync them, the sync status percentage will be shown.
