trying to iniitialize my archive appliance

SUMMARY

Unable to initialize disk following archive disk rotated

ISSUE

Unable to initialize disk following archive disk rotated

RESOLUTION

use putty to access ssh on the appliance (download http://putty.org)

run df -h
 

[[email protected] ~]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda4              14G  2.4G   11G  18% /
tmpfs                 127G  108K  127G   1% /dev/shm
/dev/sda1             226M   35M  180M  17% /boot
/dev/sda3              92G  3.9G   83G   5% /usr/bp
/dev/sdb               66T   30T   36T  46% /backups
/dev/mapper/database  820G  144G  676G  18% /var/opt/unitrends/database
/dev/md99              22T  4.1T   18T  19% /mnt/archive/0

In this case /dev/md99 is still mounted to /mnt/archive/0 showing the previous archive's storage totals

This may in addition have higher number md### mounts that need to be cleared. Mounts lower then 99 are for internal system usage and not need to clear 
cat /proc/mdstat

md4 : active raid1 sdb5[1] sda5[0]

Need to run unmount command to disconnect mount point from storage device (in this example using /dev/md99)
 
[[email protected] ~]# umount /dev/md108
[[email protected] ~]#
Once that is unmounted run mdadm --stop to clear the storage device
[[email protected] ~]# mdadm --stop /dev/md108
mdadm: stopped /dev/md108
[[email protected] ~]#

Once complete re run df -h to confirm no longer mounted and then rescan for media under UI (Configure > Appliance, Backup Copy Target, Scan for Media)

 
[[email protected] ~]# df -h

CAUSE

This can be caused by leaving the archive mount as enabled. By default best practice is to leave the archive in disabled status and allow the archive processes to mount and unmount as needed.
