Hi,
Yesterday I created some volumes in Horizon for new projects (following https://discourse.climb.ac.uk/t/creating-and-attaching-volumes-using-horizon/72) as I’ve previously done before.
Once created I proceeded to mount them. It worked perfectly for the first one as you can see:
~$ sudo mkfs -t ext4 /dev/sdc
mke2fs 1.42.13 (17-May-2015)
Discarding device blocks: done

Then, my instance suddenly stops when trying to mount the second volume I created :
~$ sudo mkfs -t ext4 /dev/sdd

ssh: connect to host 137.205.69.48 port 22: Operation timed out
So after rebooting my instance the ssh access was restored but now I’m unable to either mount the newly created volumes or even remount the previous one to its original point.
~$ mount /dev/sdb /mnt/galaxy/home/smrtanalysis/pacbio_sequences/
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.
Help please,
P.S.
Now I have several tmpfs that weren’t there before. Is that normal?
~$ df -h
