I have an AIX 6.1 volume group called
arscachevg. It is a few terabytes big and consists of 15 physical volumes. When I try to extend it with a new physical volume, I get this error:
0516-008 extendvg: LVM system call returned an unknown error code (-267). 0516-050 extendvg: Not enough descriptor area space left in this volume group. Either try adding a smaller PV or use another volume group. 0516-792 extendvg: Unable to extend volume group.
I always thought that scalable VGs had no practical limitations!
Some info from lsvg on the volume group:
PP SIZE: 256 megabyte(s) MAX PVs: 1024 TOTAL PPs: 13185 (3375360 megabytes) FREE PPs: 570 (145920 megabytes) USED PPs: 12615 (3229440 megabytes) QUORUM: 8 (Enabled) MAX LVs: 256 LVs: 11 OPEN LVs: 11 TOTAL PVs: 15 ACTIVE PVs: 15 MAX PPs per VG: 262144 LTG size (Dynamic): 256 kilobyte(s)
Anyone that can explain why this fails? The new disk is 350 GB.
I even tried
chvg -t2 arscachevg, but it is not a valid command on a scalable VG:
0516-1781 chvg: The t option is not valid for volume groups of the Scalable Volume Group type. 0516-732 chvg: Unable to change volume group arscachevg.
Very grateful if there are any AIX-LVM gurus out there that can shed some light on this. Thanks!
