My disk failed and required replacement. I backed up my data on anther disk and the hosting company removed it prior to replacing corrupted disk. Now I have a fresh install (Centos 6.10) and would like to mount the backup disk "sdb". I'm not able to do so as the disk is entirely a single partition. The command doesnt work:
[root@PGE005 ~]# mount -t ext4 /dev/sdb /mnt/disk2 mount: wrong fs type, bad option, bad superblock on /dev/sdb, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so
Model: ATA MB0500EBNCR (scsi) Disk /dev/sdb: 500GB Sector size (logical/physical): 512B/512B Partition Table: loop

[root@PGE005 ~]# lsblk -f NAME FSTYPE LABEL UUID MOUNTPOINT sdb ext4 disk2 2fd32a7c-00f9-4db9-b5bd-139cde166a14 sdc sdd sda ├─sda1 ├─sda2 ext2 af8372df-bb07-40ec-8f59-65e61576afc0 /boot ├─sda3 swap ddf30d80-0723-4e66-aa33-52c273e42464 [SWAP] ├─sda4 ext4 076sdr99-13d2-44cf-a230-49c8b3d22c7c /tmp └─sda5 ext4 3a56e728-b1e7-47a7-bc44-391ea38b8fb6 /
My backup disk is sdb. The hosting provider support said it seems that there is a compatibility issue between the partition formatter and the mounter. I appreciate any support or ideas that will help me mount the backup disk.
[root@pge005 ~]# dmesg | tail EXT4-fs (sdb): couldn't mount RDWR because of unsupported optional features (400)
