I'm looking for a good way to monitor space on all my xen DomU's. I found a command virt-df but it only tells me space and how the DomU sees the drive. I need to see mount points to know what's what.
ie:
Code:
Filesystem Size Used Available Type
fireflyold:sda1 752.1 GiB 665.0 GiB 87.2 GiB Linux ext2/3
fireflyold:sda3 152.0 MiB 39.1 MiB 112.9 MiB Linux ext2/3
CentOS5:xvda1 152.0 MiB 23.1 MiB 128.9 MiB Linux ext2/3
CentOS5:xvda3 9.5 GiB 2.8 GiB 6.7 GiB Linux ext2/3
CentOS5:xvda2 0 bytes Linux swap
F9-services:xvda1 121.6 MiB 23.9 MiB 97.7 MiB Linux ext2/3
F9-services:xvda3 9.5 GiB 2.1 GiB 7.4 GiB Linux ext2/3
OEL_5.1:xvda1 152.0 MiB 23.6 MiB 128.4 MiB Linux ext2/3
OEL_5.1:xvda2 19.0 GiB 10.1 GiB 8.9 GiB Linux ext2/3
OEL_5.1:xvda3 0 bytes Linux swap
OEL_5.1:sda4 8.5 GiB 7.3 GiB 1.2 GiB Linux ext2/3
OEL_5.1:sdc1 76.0 GiB 67.6 GiB 8.4 GiB Linux ext2/3
F9-sound:xvda1 121.6 MiB 24.0 MiB 97.6 MiB Linux ext2/3
F9-sound:xvda3 9.5 GiB 2.0 GiB 7.5 GiB Linux ext2/3
F9-sound:xvdd1 161.5 GiB 139.5 GiB 22.0 GiB Linux ext2/3
This is great for telling me available space but whats OEL_5.1:sdc1 mounted to on dom0? Is it /dev/mapper/nfsStorage-Cobbler or /dev/mapper/nfsStorage-DigitalPhotos?
I know I can ultimately get the information by reading the config files:
ie:
Code:
[root@firefly-dom0 ~]# grep xvda3 /var/lib/xend/domains/*/*
/var/lib/xend/domains/174b6882-230c-bdfd-ec19-b25bf8191dc8/config.sxp: (dev xvda3:disk)
/var/lib/xend/domains/c5804c59-c283-6747-66b8-48fb6e15920b/config.sxp: (dev xvda3:disk)
/var/lib/xend/domains/c5804c59-c283-6747-66b8-48fb6e15920c/config.sxp: (dev xvda3:disk)
/var/lib/xend/domains/c70b2713-aa47-469e-4ee3-2fe59b8e064f/config.sxp: (dev xvda3:disk)
Just wondering if there was already an all-in-one command I could use without writing some elaborate script.
Xen DomU, what's mapped to where and how much free space?
