Hi Michael,
This option would be set to on when you do a snapmirror between filers. During a snapmirror the destination volume would be adjusted as the size of the source volume.
This option will not get turned off even if you break or release the snapmirror. You need to change this manually.
Thank you, Mohan AVS NetApp Global Services

Hi,
here is the solution for my problem:
Normally it is like Adam Fox and his colleague wrote. Just adding the disks to both sites and make a 'snapmirror update' on the destination. Finish!
But, first look on the "primary" Volume if the option fs_size_fixed is set to "on" before adding the disks. I don't know why this options was set to "on", maybe once we tested to rotate the mirror. But turning the option off resolve our problem.
Thanks to all,
Michael

As I understand you have two volumes called "Volume1" that are both in snapmirrored state? One is a normal snapmirror and the other one is a DR backup of the vfiler? In this case you have to do the enlargement also on the original (third) source volume which is not in snapmirrored state and therefore does not have the fs_size_fixed set to "on". The size of the filesystem of snapmirrored volumes will adapt to the source volume after the next scheduled update as Adam pointed out earlier (of course you have to add the same amount of space to each of them first).

Hallo,
maybe my initial situation was not clear:
On the "main site" I spent VfilerA a new disk. Volume1 before "vol add" : 201 GB Volume1 after "vol add" : also 201 GB
vol status -b Volume1: Vol Size (blocks) FS Size (blocks)
76996480 61597184
The filer notified that "..the disk was successfully added to volume Volume1" IMHO this results because Volume1 is in "snapmirrored-state" an the option "fs_size_fixed" is set "on".
On the "desaster site" I spent VfilerA' (vfiler dr) also a new disk for volume Volume1. Same results.
I think I must break the mirror but is this possible without side effects on VfilerA because he is in "vfiler dr"
Thanks a lot

You don't need to do this. It looks like you are doing Volume SnapMirror. All you have to do is add the disks to both volumes. You won't see the change on the destination until the next update, then the destination will become the size of the source.

We perform "snapmirror quiesce" then "snapmirror break" then turn off "fs_size_fixed".

Hi,
I have a problem to enlarge a volume owned by a "dr"-vfiler.
Vfiler1 Vfiler1 (dr backup) |--> vol1 |-->vol1
It was possible to add a disk to vol1 on both sites. But I can't disable
the
volume option "fixed fs_size", because vol1 is in "snapmirrored-state".
How can I enlarge the volume without deleting the dr-filer?
Thanks for help,
Michael

Enlarging a volume which is the source of a snapmirror should imply the following steps : 1 - enlarge the destination volume (vol add dest 6) 2 - enlarge the source volume (vol add source 6) 3 - that's all !
snapmirror do all the rest of the job
the option fs_size_fixed should remain to on on the dest volume it permits the dest vol to be of the size before-the-enlargement, even if you enlarge it, until a new update
the only time you would pass this option off is when you want to turn your dest volume writable and usable as a normal volume in this case, you break the mirror and pass the option off
