lvextend and strict policy

[franlo]

Hello,

I have a silly problem. I have a SuperDome IA64 11.23 connect to 2 XP1024 bays (xp1 and xp2) throuh 2 brocade switch in fabric mod.

I have a Vg "vgPRD" of 1 To, wich have NO pvg and have 13238 free PE (Pe size is 16Mo) : 200Mo free. this vg have 40 PV in xp1 and 40 pv in xp2.

I have a lvol (lvsapmnt) of 2Go mirored on each xp bay. his alocation is "PVG-strict/distributed".

I tried to extend this lvol but i have : "Not enough free physical extents available"

the distribution of lvol's pe is : distributed between 40 pv in xp1, mirrored and distributed on 40 pv in xp2.

I don't want to loose distributed mode.

I've already done "lvchange -C n lvol" to delete contigus mod, but i don't manage to extend lvol.

All the 80 PV have enouth free PE.

I think it's a allocation mod problem but how can i extend it ?



thanks a lot for your help.

regards
Francois

[Deoncia Grayson_1]

could you just post a regualar lvdisplay -v on any lvol without grepping out anything ???

[Torsten.]

Looks like you need free space on every PV (LUN) used in this VG do continue distributing. You need to check this.(pvdisplay vs. xpinfo)

[franlo]

hello

here a file with vgdisplay, lvdisplay, one pvdisplay and xpinfo.

if i look pv distribution of one pv, i have the following :
/dev/vgPRD/lvcft 00 -> 01
/dev/vgPRD/lvora 02
/dev/vgPRD/lvoraPRD 03 -> 34
/dev/vgPRD/lvoracli 35 -> 36
/dev/vgPRD/lvquest 37 -> 38
/dev/vgPRD/lvsapmnt 39 -> 42
/dev/vgPRD/lvstage 43 -> 50
AGAIN /dev/vgPRD/lvcft 51 -> 52
/dev/vgPRD/lvinter1 53 -> 58
/dev/vgPRD/lvuniv 59 -> 63
/dev/vgPRD/lvusrsap 64 ->65
/dev/vgPRD/lvarch 66 -> 401
/dev/vgPRD/lvtrans 402 -> 456
AGAIN /dev/vgPRD/lvinter1 457 -> 564
AGAIN /dev/vgPRD/lvcft 564 -> 569


I would like to extend lvsapmnt on pe#570 to pe#574 on this pv. This lvol should not be contigus, and its le are round robbin distributed on all pv of vg (80pv) in PVG-strict/distributed mode (there are no pvg)


thank for your help

regards

Francois

Shalom,

Suggestions,

How about breaking any mirrors prior to trying to lvextend.

It seems the intial setup is a little jumbled or disorganized.

I've found it necessary due to my own issues to regorganize completely. This means shutting down any databases, backing up all data to tape, recreating the volume group, logical volumes and restoring the data.

Srict allocation policies are done for a good reason and changing this might be a bad idea for long term data integrity.

SEP

[Torsten.]

The LVOL allocation policy set is "distributed", it is similar to "striped".

For this reason you need to have free space on every pvol used by this lvol.

You need to find the minimum number of free PEs on all pvols and extend to this value.

example:

PV Name /dev/dsk/c125t3d4
Free PE 173
PV Name /dev/dsk/c127t3d0
Free PE 160

You can only use the 160 free PEs.
