No answer to your question, but a cautionary note that AFAIK lvm snapshots are still marked experimental in the 2.6 kernel. I know I've had far more luck with them in 2.4 than I ever have in 2.6. I posted earlier that my SuSE 10.1 snapshot experience was improved, but I'm still definately getting errors. ie. failed snapshots.
I wasn't aware of this. I've had a complete lockups of a system twice while creating a snapshot.
I take snapshots daily, 99% of them successful, and I didn't understand these two lockups. (no difference compared to the other days afaik...)
Are you generally staying away from lvm snapshots..? Anyone else seeing that it's not 100% stable..?

mj, At least for me snapshots are not causing lockups. I'm just not able to mount the newly created snapshot. On the one fileserver I've updated to a 2.6 kernel, I do a snapshot every night of 3 different lvm volumes.. Looking at the last 30 days logs I had volume 1 - 1 failure volume 2 - 19 failures volume 3 - 26 failures You can see why I'm not very comfortable with LVM snapshots yet. Also, I monitor the redhat lvm mailing list and they get lots of posts about snapshots. The answer had typically been that it is still experimental, so don't use it in production. Recently they have been saying new patches have been posted to LKML, so try the latest and greatest vanilla/redhat kernel. I don't know if any of those recent fixes have made it into the SuSE 10.1 kernel or not. I hope not, because then I can hope that 10.2 will be better.
