Brief description of the problem

Running 4.5.8-0
Recently plugged in two disks that came from a previous backup appliance. When I go to rescan disks to see if it shows up this error occurs. I am fairly new to rockstor and I am not sure what to make of this error. When moving the disks to a different spot on the backplane it still has the error. I just pulled the two disks and I can hit the rescan button when they are not connected. I thought maybe it didnt like that they were recently added and it did not like me hot swapping the disks in and let it reboot with the drives in. It did not make a difference.

Detailed step by step instructions to reproduce the problem

Only steps are to navigate in the gui, click disks then click the rescan button

Hi @adams , and welcome to Rockstor!

Disk management is more @phillxnet’s expertise than mine, but let’s see if I can at least help move things along a bit. It would indeed be helpful to see what your system is seeing; would you be able to provide us with the outputs from the following?

lsblk -P -p -o NAME,MODEL,SERIAL,SIZE,TRAN,VENDOR,HCTL,TYPE,FSTYPE,LABEL,UUID

and

btrfs fi show

Im trying to add two 2tb drives and make another pool but it is not showing up under disks. I meant to add that if I disconnect the two drives I can hit rescan I get no errors. These are known good drives. Am I correct in thinking there isn’t any prep I need to do before adding the disks?

Im sorry I had the two disks not plugged in. Did both commands again while the 2 extra drives were plugged in. The 2nd command btrfs fi show did not look any different.

Looks like these 2 disks have, among other things, some ntfs partitions on them (/dev/sdi & /dev/sdi1, and /dev/sdh & /dev/sdh1 to 4)? The VFAT partition listed there I think corresponds to FAT32.

You likely have to clean those up (i.e. wipe the disks) before you can add them. Would make sense to have them as one large partition to deal with on each disk.
