Re: [zfs-discuss] ZFS problems in dCache

2007-08-08 Thread Steven Gelsie
I think I am having the same problem using a different application (Windchill). zfs is consuming hugh amounts of memory and system (T2000) is performing poorly. Occasionally it will take a long time (several hours) to do a snapshot. Normally a snapshot will take a second or two. The

[zfs-discuss] is send/receive incremental
