Disk is apparently in use by the system
- by Shaun
I've just fitted two disks to my home server. I'm trying to format and then raid them but I'm getting a problem that hours of Googling hasn't resolved this.
The error that I'm getting is:
# mkfs.ext3 /dev/sdb1
mke2fs 1.39 (29-May-2006)
/dev/sdb1 is apparently in use by the system; will not make a filesystem here!
# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 4.0G 1.9G 2.0G 49% /
none 380M 0 380M 0% /dev/shm
/opt/xensource/packages/iso/XenCenter.iso
51M 51M 0 100% /var/xen/xc-install
# mount -t ext3 /dev/sdb1 /mnt/b
mount: /dev/sdb1 already mounted or /mnt/b busy
I'm new to this and it's got me beat. I wouldn't ask if I hadn't done my research first. Thanks.
