hi all,
Pls help. First of all , please know that I am not technical at all and I may even have done things wrongly all along, but here is my situation which I really hope someone can help.
I have a NAS TS 251A, with 2 Hardrives. Recently I got errors saying Disk 2 is over 50 degrees hot and etc etc, I was to replace it soon, finally yesterday it really failed.
So today i remove it and replaced it with an older hard drive, hoping it will autosync to it so that at least I will have another copy until I get a new drive.
But it kept saying error on volume / pool and will not backup/sync. So I removed disk 2 and reboot the NAD, but now one of my storage pool is MISSING.
So my question is , how can I restore that storage pool back out , should I shut the NAS down now etc ? thank you
all my kids and parents photos are in there ! pls pls help asap

Re: Missing Storage Pool, urgent help
You discovered the hard way why you need external backups at all times.
What was the disk configuration ? RAID1,RAID0, Pooled Single Disks, Spanning JBOD ?
If anything else other than RAID1, you array is bust with a single swapped drive.

Re: Missing Storage Pool, urgent help
are you using the admin account on your NAS to login via SSH? .. with that many permission issues you probably are not .. correct ?
