Snapdrive [ WARN] SD-10015 Switch to the best-effort mode


While doing Backups using SMO and Snapdrive we see now and then the following Warning Message :

[ WARN] SD-10015: Snapdrive command "/usr/sbin/snapdrive snap create -fs /DXXX/u01 -snapname dxxx_smo_h_daily_20151009_053621_1_8a9a9ca5504aabb201504aabb7650001_0 -unrelated" generated warning: 0001-904 Warning: Attempting to take a crash consistent snapshot.
Switching to the best-effort mode


What does this Message mean ? Can it be ignored as long as it is not arising regularly ?


Thanks Eric

Eric -


I'm guessing you're using ASM ?

It means SnapDrive had a problem while trying to snapshot multiple LUNs in a consistency group.


See the Snapdrive documentation: Crash-consistent Snapshot copies


SMO is designed to fail 'safe'' - the snapshots are probably all good on these backups, or SMO wouldn't mark them as succesful.


I wouldn't be worried about it, but you may want to do a test clone of the DB from one of the backups with the error message.

I hope this response has been helpful to you.
