Reply-To: LVM general discussion and development List-Id: LVM general discussion and development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , List-Id: Content-Type: text/plain; charset="us-ascii"; format="flowed" To: linux-lvm@redhat.com I have Fedora 8 system with operating system installed on a small (18GB) hard disk. A second disk (320GB) is being added to hold user data. Now that there is a second disk, I would like to alter the existing LVs so they have mirrors. Is this possible? I couldn't find anything that looked promising on the lvchange(8) man page. - Don ========================================================= Some of the gory details: ------------------------- # lvmdiskscan /dev/sda1 [ 196.08 MB] /dev/sda2 [ 16.75 GB] LVM physical volume /dev/sdb1 [ 196.08 MB] /dev/sdb2 [ 297.90 GB] LVM physical volume 0 disks 2 partitions 0 LVM physical volume whole disks 2 LVM physical volumes # pvscan PV /dev/sda2 VG vg00 lvm2 [16.75 GB / 32.00 MB free] PV /dev/sdb2 VG vg00 lvm2 [297.88 GB / 297.88 GB free] Total: 2 [314.62 GB] / in use: 2 [314.62 GB] / in no VG: 0 [0 ] # vgs VG #PV #LV #SN Attr VSize VFree vg00 2 5 0 wz--n- 314.62G 297.91G # lvscan ACTIVE '/dev/vg00/lv00_root' [8.00 GB] inherit ACTIVE '/dev/vg00/lv04_home' [4.22 GB] inherit ACTIVE '/dev/vg00/lv02_var' [1.50 GB] inherit ACTIVE '/dev/vg00/lv03_varlog' [2.00 GB] inherit ACTIVE '/dev/vg00/lv01_swap' [1.00 GB] inherit -- - Don Buchholz, Sr. Systems Admin. - iMove, Inc., 1732 NW Quimby St., Suite #200, Portland, Oregon 97209 - 503.273.2926 (phone) 503.221.2172 (fax)
