I just resized a .vdi from my host from 15.5G to 120G. I tried to resize the partition from the guest (ubuntu server) using
root@ubuntu:~# sudo resize2fs /dev/sda2 115G resize2fs 1.42.13 (17-May-2015) resize2fs: Attempt to read block from filesystem resulted in short read while trying to open /dev/sda2 Couldn't find valid filesystem superblock.
Now, according to my understanding of the situation
/dev/sda2 is corrupt. However, my server-VM still works fine and has no problems running on the partition.
fdisk -l /dev/sda outputs:
Disk /dev/sda: 120 GiB, 128849018880 bytes, 251658240 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x32955267 Device Boot Start End Sectors Size Id Type /dev/sda1 * 2048 999423 997376 487M 83 Linux /dev/sda2 1001470 33552383 32550914 15.5G 5 Extended /dev/sda5 1001472 33552383 32550912 15.5G 8e Linux LVM
Now to my question: Is this normal and healthy for the server and if not, how do I fix it?
