IHAC which has all its volume options to fractional_reserve=0 and garantee=volume.
Each time SDW 6.x creates a flexclone, it creates it with garantee=none (for SMSQL DBCC Check purpose) consequences are that the fractional_reserve is automatically change to 100%, the results are presented here for illustration, every night it gives a "FULL VOLUME" alert:
Tue Dec 14 02:06:38 CET [XXXXXXXX: wafl.volume.clone.fractional_rsrv.changed:info]: Fractional reservation for clone 'sdw_cl_XXXXXX_log_0' was changed to 100 percent because guarantee is set to 'file' or 'none'.

Tue Dec 14 02:07:00 CET [XXXXXXX: monitor.globalStatus.nonCritical:warning]: /vol/sdw_cl_xxxxxx_log_0 is full (using or reserving 100% of space and 0% of inodes, using 72% of reserve).
Is there any options in Snapdrive 6.x to explicitely force the space reservartion on Flexclone just like we can do on SDU 4.X to avoid this behaviour ?
