Good evening! Here at work we are considering switching our linux-based NAS systems to OpenSolaris because of ZFS, but I have some doubts.
Imagine we have a 500Gb hard disk full of data. We do an snapshot of the data, for backup or whatever, then we delete those files and try to save another 500 gigs of info there. How does the copy-on-write manage the free space? What would happen in that case? Would it look like the hard disk is empty to the network users when in fact is full because of the snapshot? Would the snapshot be overwritten or the system would warn there is no free space? Thanks in advance. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
