Hi,
I am new to this list, seeking for some help.
I have setup LVM2 under debian sarge (2.6.8-k7 kernel).
I originally created a volumen group (nasvg) on 4 x ST3200822A ATA DISK drives. I created a stripped logical volume spanning these 4 disks and using up al PE's available. I then attached two aditional ST3200822A ATA DISK drives and I would now want to resive my logical volumen to use al the PE's provided by the two new disks. The problem is I can't extend the logical volume, getting the following error:
gollum:~# lvextend -L+1G /dev/nasvg/naslv
Using stripesize of last segment 64KB
Extending logical volume naslv to 746.23 GB
Insufficient allocatable extents suitable for parallel use for logical volume naslv: 191036 required
I have been googl'ing and it seems that this has to do with restrictions on resizing sttriped LV's. However, the information I have found says the restrictions no longer apply to LVM2.
Any help would be appreciated. I'm thinking of creating a linear lv spanning al 6 disks but this would mean backing up ~600gb of data which could be a pain...
Here is my output for both vgdisplay and lvdisplay.
gollum:~# vgdisplay --- Volume group --- VG Name nasvg System ID Format lvm2 Metadata Areas 6 Metadata Sequence No 25 VG Access read/write VG Status resizable MAX LV 0 Cur LV 1 Open LV 1 Max PV 0 Cur PV 6 Act PV 6 VG Size 1.09 TB PE Size 4.00 MB Total PE 286168 Alloc PE / Size 190780 / 745.23 GB Free PE / Size 95388 / 372.61 GB VG UUID LWqtTF-F8vA-yjXt-AYwK-yFQr-skDa-s9UVRC

Thanks, and merry Christmas! Olmo.
