I have installed a FAS3240 Metrocluster with DoT 8.0.1 7-mode two days ago, and the one thing that I cannot clear out is the following error:
MC3240B> aggr show_space aggr0

fs_size_fixed=off, snapshot_autodelete=on, lost_write_protect=on,
Can someone tell if this is the reason for the error? And is there a solution? I've been searching NOW up and down but apparently not well enough! Syslog translator gives me a fantastic : "there is no space on device".
Any help greatly appreciated! Thanks
Solved! SEE THE SOLUTION

The snap reserve on aggregate aggr0 is currently set to 0. As a result, the filer has no space allocated for the SyncMirror snapshot. Hence, we give the error of no space left on device.
The recommendation is to have the snap reserve for aggregates set to 5% in SyncMirror configuration. You can set the snap reserve by issuing the following
MC3240B> snap reserve -A aggr0 5

Thank you sowens!
That was what I was looking for. Since I couldn't find it, I was fearing that it was only at creation time that I could add the snap reserve.
It's working fine now.
