I've been seeing read and write performance pathologies with Linux ext3 over iSCSI to zvols, especially with small writes. Does running a journalled filesystem to a zvol turn the block storage into swiss cheese? I am considering serving ext3 journals (and possibly swap too) off a raw, hardware-mirrored device. Before I do (and I'll write up any results) I'd like to know if anyone tried/addressed this already.
The lack of tools to analyse ZFS fragmentation means I'm somewhat in the dark, so I'm just likely to suck it and see. JG _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
