Hi, The following blocks are from a guest. I have the block mintaka--vg-swap_1 which I want to remove (it was created when the guest was first made). Then I want the freed space be allocated to mintaka--vg-root (so that it will be expanded to 7.7GB). Does anybody know what I should do? (I know that this is not related to the usage of virsh, but I'm not sure where I should ask this question as I don't quite understand how /dev/mapper works) Thanks. pengy@saiph:~$ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sr0 11:0 1 1024M 0 rom vda 253:0 0 50G 0 disk ├─vda1 253:1 0 243M 0 part /boot ├─vda2 253:2 0 1K 0 part └─vda5 253:5 0 7.8G 0 part ├─mintaka--vg-root (dm-0) 252:0 0 3.7G 0 lvm / └─mintaka--vg-swap_1 (dm-1) 252:1 0 4G 0 lvm vdb 253:16 0 256G 0 disk └─vdb1 253:17 0 256G 0 part [SWAP] pengy@saiph:~$ ll /dev/mapper/mintaka--vg-swap_1 lrwxrwxrwx 1 root root 7 May 11 18:53 /dev/mapper/mintaka--vg-swap_1 -> ../dm-1 pengy@saiph:~$ df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/mintaka--vg-root 3.7G 3.4G 78M 98% / none 4.0K 0 4.0K 0% /sys/fs/cgroup udev 106G 12K 106G 1% /dev tmpfs 22G 392K 22G 1% /run none 5.0M 0 5.0M 0% /run/lock none 106G 0 106G 0% /run/shm none 100M 0 100M 0% /run/user /dev/vda1 236M 88M 136M 40% /boot pengy@saiph:~$ swapon -s Filename Type Size Used Priority /dev/vdb1 partition 268435420 0 -1 pengy@saiph:~$ blkid /dev/vda1: UUID="df99ebcd-2dcf-4703-ae7c-0e5ec48cc4ca" TYPE="ext2" /dev/vda5: UUID="Uz8Imz-aADL-420e-CWo1-sdrS-Zufj-1UFF5u" TYPE="LVM2_member" /dev/vdb1: UUID="730e895a-d3ad-4911-993f-dae39a190271" TYPE="swap" /dev/mapper/mintaka--vg-root: UUID="4bc04e08-add6-4f92-868f-81dce4560adc" TYPE="ext4" /dev/mapper/mintaka--vg-swap_1: UUID="302daede-eb31-4db5-ad17-6d048931e86e" TYPE="swap" pengy@saiph:~$ sudo fdisk -l Disk /dev/vda: 53.7 GB, 53687091200 bytes 16 heads, 63 sectors/track, 104025 cylinders, total 104857600 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0008a759 Device Boot Start End Blocks Id System /dev/vda1 * 2048 499711 248832 83 Linux /dev/vda2 501758 16775167 8136705 5 Extended /dev/vda5 501760 16775167 8136704 8e Linux LVM Disk /dev/vdb: 274.9 GB, 274877906944 bytes 16 heads, 63 sectors/track, 532610 cylinders, total 536870912 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/vdb1 63 536870911 268435424+ 83 Linux Disk /dev/mapper/mintaka--vg-root: 4005 MB, 4005560320 bytes 255 heads, 63 sectors/track, 486 cylinders, total 7823360 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/mapper/mintaka--vg-root doesn't contain a valid partition table Disk /dev/mapper/mintaka--vg-swap_1: 4290 MB, 4290772992 bytes 255 heads, 63 sectors/track, 521 cylinders, total 8380416 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/mapper/mintaka--vg-swap_1 doesn't contain a valid partition table -- Regards, Peng _______________________________________________ virt-tools-list mailing list virt-tools-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/virt-tools-list
