And a "pvdisplay" do not see any new physical extents available (perhaps I'm missing something on this, I'm totally new from this and way long to be totally cool with it): --- * before the rmmod/modprobe (see /dev/sdb): --- [root at X install]# fdisk -l Disk /dev/sda: 146.6 GB, 146695782400 bytes 255 heads, 63 sectors/track, 17834 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 13 104391 83 Linux /dev/sda2 14 17834 143147182+ 8e Linux LVM Disk /dev/sdb: 700.0 GB, 700079669248 bytes 255 heads, 63 sectors/track, 85113 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk /dev/sdb doesn't contain a valid partition table Disk /dev/sdc: 233.0 GB, 233001975808 bytes 255 heads, 63 sectors/track, 28327 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk /dev/sdc doesn't contain a valid partition table --- After: --- [root at X install]# fdisk -l Disk /dev/sda: 146.6 GB, 146695782400 bytes 255 heads, 63 sectors/track, 17834 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 13 104391 83 Linux /dev/sda2 14 17834 143147182+ 8e Linux LVM Disk /dev/sdd: 933.0 GB, 933081645056 bytes 255 heads, 63 sectors/track, 113440 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk /dev/sdd doesn't contain a valid partition table Disk /dev/sde: 233.0 GB, 233001975808 bytes 255 heads, 63 sectors/track, 28327 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk /dev/sde doesn't contain a valid partition table --- Should I be worried about the "non-valid partition" table message? I can use the LV (mount and work with files), so I don't know if it is a problem. Maybe the fact that there is no partition table for fdisk is why I can't make it grow? I mean, maybe I should have create first one partition (type LVM), then create a second one with the extra size ? Here is what I've done to create the logical volume: --- [root at X ~]# pvcreate /dev/sdb [root at X ~]# vgcreate VG-B /dev/sdb [root at X ~]# lvcreate -l 166911 VG-B -n LV-B // Note: 166911 is the maximum number of physical extents available before the grow [root at X ~]# mkfs.ext3 /dev/VG-B/LV-B --- from there I could use the volume. --- [root at onyx install]# pvdisplay --- Physical volume --- PV Name /dev/sde VG Name VG-C PV Size 217.00 GB / not usable 0 Allocatable yes (but full) PE Size (KByte) 4096 Total PE 55551 Free PE 0 Allocated PE 55551 PV UUID w3Q4hA-ALnz-4UuH-fdBB-FGOT-Rn2t-4iG2Vv --- Physical volume --- PV Name /dev/sdd VG Name VG-B PV Size 652.00 GB / not usable 0 Allocatable yes (but full) PE Size (KByte) 4096 Total PE 166911 Free PE 0 Allocated PE 166911 PV UUID AFcoa6-6eJl-AAd3-G0Vt-OTXR-niPn-3bTLXu --- Physical volume --- PV Name /dev/sda2 VG Name VolGroup00 PV Size 136.50 GB / not usable 0 Allocatable yes PE Size (KByte) 32768 Total PE 4368 Free PE 1 Allocated PE 4367 PV UUID OjQEXi-u3F8-wCXO-1eZY-W2j0-iZyG-5PwwnB ---- -------------- next part -------------- An HTML attachment was scrubbed...
