Restore storage pools

[attichris]

Hi,

I had to replace my unit. I had 3 single disk pools, I now only have 1 being recognised. Is there a way I can get the data from other 2 disks back? When I try to create a storage pool again it says the data on the disk will be removed. Will i have to back the the disks up to a linux machine first?

thanks,
chris

Hi Chris, what did you do to your device? What is the model number and OS version?

Hello attichris and TMroy,

I encounter exact issue:

I created a RAID0 copied all the files last night. Now, this morning every time I try to access the NAS it wants me to configure everything other than static-IP. I can access the NAS, I see all the folder

/mnt# ls
Family appdata bootdev iPhoneBackup md0 public usb usbshare1

cd public
-bash: cd: public: Not a directory

When I try to copy a file to /mnt/public, looks like I can

# cp CRW_0210.jpeg /mnt/public

Does not throw any errors

But if I try to go to /mnt/public, I get following error


# cd /mnt/public
-bash: cd: /mnt/public: Not a directory

So, looks like that RAID and virtual disk do exist, but some wired reason I can't access those.

Checked the /etc/fstab and stab is empty.

Any suggestions to fix this issue ASAP will be gr8ly appreciated

May I know your model number, TOS version and what hard drive you installed?

I ran e2fsck form the cli and fixed hard drive issue and everything stared working.

Thank you for your update.
