At one of my Customer i have the following Problem:
VM-Server installen 6 Week ago with UCS 4.3, 4 cores, 8 GB Ram, 300 GB HDD, DC Slave and Kopano (from the App Center). 3 Users an 5 Mailboxes with an size over all from 15 GB.
Installed with LVM and one Partition. Now the systems has a Problem with an full HDD.
If I use df -h i got the following output:
Size: 282 G Used: 263 G Free: 4G
With du -hs (from the root) i got this:
used: 81 G (Including 63 G Backup on NFS-Share on an 2nd File server)
If i use du -hs * from root and summerize by hand there are 81 G used.
How can I relaim the unuse space why does this happen?
The Kopano Support has no resolition and no Idea.
I thing there is an Bug at Patitioning in the Installer.
a nice programm to see where your disk space went is ncdu. On ucs you need to enable unmaintained to install it (you can disable the unmaintained repos afterwards).
I’d also check the disk usage when externally mounted partitions are unmounted, just in case the mount was not in place when running the backup.
EDIT: Just noticed the df-output showing /dev/mapper/vg_ucs_root which is indeed strange. Usually there should be no files in /dev and find /dev -type f should give no results.
BTW: screenshots are hard to read and to search. better copy&paste and use preformatted text.
with your Hint i thing I have the reaso. -> The System don’t delete the files on the Disk, only in The NFS Share. After unmouting the Backup NFS Share there wherer 246 GB of old Backupfiles in The Folder /Backup. These Files i Cant see with mounted NFS Share to /Backup.
After installeration I Crated a empty Folder an mount thos to the NFS Share on the UCS File server with this command in the fstab:
192.168.7.13:Data/98\040Dasi/DD-SRV-Kopano /Backup nfs4 auto 0 0
attached the Information from The Console (Bevore umount, after Umount and after Delete old Files and remount)
