Just testing the new FB 7beta3 - installed from the ISO-images.
System is running on an SCSI 9GB disk, the machine has 750MHz with 512MB
Ram and the zfs is using 8 ATA Disks, 4x120GB and 4x160GB connected to
Promise Fasttrak TX2 (with no configs).
Creating the ZFS using "zpool create tank raidz adX" was fascinating,
after a few seconds I have 920GB disk space - WoW.
kmem_min is 256MB.
Next step was creating /tank/CTM and /tank/CVS, then running
pwd:/tank/CVS/ctm -vvv /tank/CTM/* and while extracting it suddenly hangs.
Nice: I can login in new sessions.
Bad: Systems hangs, sync runs in nirwana and trying to reboot produces
"Deadly processes found, won't die" and hangs up the reboot.
just for information ;)
Bye
Stefan

Re: Big volumes, small files ... Though I don't have any direct experience with it, my impression is that people are using it in production systems successfully - so a description of your specific reservations would be useful. ... IIRC it occurs as part of an already-existing data copy operation at a very low level in the disk read/write routines, and at close to memory-streaming speeds. ... What can move at close to memory speeds is the *CPU* overhead involved in the checks, and it can piggyback on a memory-to-memory data move that is happening anyway. ... My impression is that *some* customers have workloads that have found ZFS to be very stable already, while others push corner cases that are still uncovering bugs. ... (comp.arch.storage)
