Hi, I am running LVM on top of a large RAID controller with a 16-drive capability (of which just 4 disks are currently active). The RAID array appears as a single SCSI disk, "/dev/sda". A quick summary of the LVM information is below. tiger:~# lvm version LVM version: 2.01.04 (2005-02-09) Library version: 1.01.00-ioctl (2005-01-17) Driver version: 4.4.0 tiger:~# pvs PV VG Fmt Attr PSize PFree /dev/sda storage lvm2 a- 745.05G 39.05G tiger:~# vgs VG #PV #LV #SN Attr VSize VFree storage 1 3 0 wz--n 745.05G 39.05G tiger:~# lvs LV VG Attr LSize Origin Snap% Move Copy% home storage -wi-ao 2.00G root storage -wi-ao 2.00G var storage -wi-ao 2.00G main storage -wi-ao 700.0G tiger:~# mount /dev/mapper/storage-root on / type reiserfs (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) tmpfs on /dev/shm type tmpfs (rw) /dev/hda1 on /boot type ext3 (rw,noatime) /dev/mapper/storage-home on /home type reiserfs (rw) /dev/mapper/storage-var on /var type reiserfs (rw) /dev/mapper/storage-main on /main type reiserfs (rw) usbfs on /proc/bus/usb type usbfs (rw) tmpfs on /dev type tmpfs (rw,size=10M,mode=0755) tiger:~# I now need to increase my RAID capacity. I can increase the physical RAID capacity by adding another disk to the controller and getting it to re-build the array in the background, thus increasing the size of "/dev/sda", but I am not clear as to how I can increase the PV size in LVM. I have seen some references to a "pvresize" command, but it isn't in the latest 2.01.15 stable release (although it does appear in the 2.02.02 development release). Hence, my questions are: - Is it possible to re-size a PV whilst the system is online using the 2.01.15 tools? - Is it possible to re-size a PV whilst the system is online using the 2.02.02 tools? - How "stable" are the 2.02.02 tools, and are there any specific bugs in them that may cause problems during typical usage. Thanks, Roger _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
