unable to mount additional hdd

itachikonoha

hi, I've a hostc 5 tb storage server. Today I reinstalled the OS but unable to mount the additional storage after that. I am assuming when I reinstall, the secondary storage will remain unaffect and only the primary disk will be formatted.

lsblk output

NAME    MAJ:MIN RM   SIZE RO TYPE MOUNTPOINTS
sda       8:0    0    40G  0 disk
├─sda1    8:1    0    39G  0 part /
├─sda14   8:14   0     4M  0 part

└─sda16 259:0    0   913M  0 part /boot
sdb       8:16   0   4.9T  0 disk
sr0      11:0    1     4M  0 rom
sr1      11:1    1  1024M  0 rom
sr2      11:2    1 598.4M  0 rom

Since there is no devices under sdb, I am unable to mount.

fdisk -l produces (for secondary disk):

Disk /dev/sdb: 4.88 TiB, 5368709120000 bytes, 10485760000 sectors
Disk model: QEMU HARDDISK
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

I haven't used linux that much so unable to move forward from here. If paritition table is indeed lost, without losing data, is it possible to recover?

Request to mods: Please move to appropriate section. I still don't know how to create a thread in a specific category in vanilla forum

Edit: Ah, looks like partition table indeed lost. Better reach out to support.

You need to partition it first, then format it, and then mount it.

Use something like fdisk /dev/sdb to create partitions.

Once partitions are created, use something like mkfs -t ext4 /dev/sdb1 to format it to the FS you want.

And then you can mount it.

It had 4TB data before reinstalling the primary. I guess I have to accept that data have been lost.....

Hi,

assumption is the mother of every fuck up

OS reinstall via template is with all providers i know a complete reinstall of the server.

( delete server -> create server ).

Edit: try with testdisk if you are lucky....

Have you tried asking it nicely to get mounted?
