VCMP space disk allocation explanations
Hello,
Can please someone help me to understand the disk allocation of this VCMP system?
1/ Total physical disk space is : 400GB according to fdisk:
[root@XXX:Active:Standalone] config fdisk -l
Disk /dev/sda: 400.0 GB, 400088457216 bytes
255 heads, 63 sectors/track, 48641 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 * 1 48641 390707808 8e Linux LVM
2/ Guests vdisks use 100G of lvm space but... (so you can guess 500GB used... :/)
[root@XXX:Active:Standalone] config ls -lh /shared/vmdisks/
total 23G
drwx------ 2 root root 16K Apr 8 16:45 lost+found
-rw-r--r-- 1 root root 100G Jun 23 11:45 GUEST1.img
-rw-r--r-- 1 root root 23 Jun 22 15:25 GUEST1.info
-rw-r--r-- 1 root root 100G Jun 23 11:45 GUEST2.img
-rw-r--r-- 1 root root 23 Jun 22 15:25 GUEST2.info
-rw-r--r-- 1 root root 100G Jun 23 11:45 GUEST3.img
-rw-r--r-- 1 root root 23 Jun 22 15:25 GUEST3.info
-rw-r--r-- 1 root root 100G Jun 23 11:45 GUEST4.img
-rw-r--r-- 1 root root 23 Jun 22 15:28 GUEST4.info
-rw-r--r-- 1 root root 100G Jun 23 11:45 GUEST5.img
-rw-r--r-- 1 root root 23 Jun 22 15:25 GUEST5.info
3/ ... but the physical space usage is as below:
[root@XXX:Active:Standalone] config tmsh show vcmp virtual-disk detail
--------------------------------------------------------
Sys::Vcmp::VirtualDisk
Name Operating System Status Disk Use (bytes)
--------------------------------------------------------
GUEST1.img tmos in-use 4.6G
GUEST2.img tmos in-use 4.4G
GUEST3.img tmos in-use 4.5G
GUEST4.img tmos in-use 4.3G
GUEST5.img tmos in-use 4.5G
4/ and indeed pysically this matches (4.6 + 4.4 + 4.5 + 4.3 + 4.5 = 23 GB) and confirmed with command du:
[root@XXX:Active:Standalone] config du -hs /shared/vmdisks/
23G /shared/vmdisks/
5/ But when I run command df I can't summ the disk space to reach 400GB:
[root@XXX:Active:Standalone] config df -h

/dev/mapper/vg--db--sda-app.vcmp.dat.vmdisks
277G 23G 240G 9% /shared/vmdisks
How should I interpret all thoses disk usage values to figure out the real explanation?
Thanks for your help. Kind regards.

Yes, those set.N items are related to the install locations HD1.N. If you want to destroy one, you can issue "tmsh delete sys software volume HD1.N", either in the guest or the host, wherever you're trying to eke out more free disk space.
