Show Physical mounted drives

Hi,

We have just had a situation where the external USB drive for our dedicated server dis mounted without us realizing and the server started backing up to itself at /mnt/usbdrive.

we only realized this when the server ran out of space and things stopped working. So my question is ....

1. Is there any command line that can be run to check if the backup drive is mounted correctly to /mnt/usbdrive
2. Is there any automated way of finding out if the backup drive dismounted?

Regards
Andy

 

Hi Michael,

Thank you for the reply. Please can you tell me what the below command actually does? Would this also work?

grep mnt /proc/mounts

 

Hi Michael,

I ran the mount command and got the below information. When the external back up drive was plugged the first time is was /dev/sdb, i have unplugged it and plugged it back in a second time and now its on /dev/sdc, i have mounted it with 'mount /dev/sdc /mnt/usbdrive' but the below output is now showing two drives mounted to /mnt/usbdrive. Is that going to cause issues?

root@server [~]# mount
/dev/mapper/vg_server-lv_root on / type ext4 (rw,usrjquota=quota.user,jqfmt=vfsv0)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw)
/dev/sda1 on /boot type ext4 (rw)
/dev/mapper/vg_server-lv_home on /home type ext4 (rw,usrjquota=quota.user,jqfmt=vfsv0)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
/tmp on /var/tmp type none (rw,noexec,nosuid,bind)
/dev/sdb on /mnt/usbdrive type ext4 (rw)
/dev/sdc on /mnt/usbdrive type ext4 (rw)

 

Michael,

I have just look at my fstab file, I don't see any mention of /dev/sdc. Here is the file contents :


#
# /etc/fstab
# Created by anaconda on Sat Mar 14 20:08:35 2015
#
# Accessible filesystems, by reference, are maintained under '/dev/disk'

/dev/mapper/vg_server-lv_swap swap swap defaults 0 0
tmpfs /dev/shm tmpfs defaults 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
sysfs /sys sysfs defaults 0 0
proc /proc proc defaults 0 0

 

No matter, just un mounted it with umount and remounted it correctly, that got rid of the entry. Would still like to know why it isn't showing in fstab though?
