Re: [zfs-discuss] ZFS very slow under xVM

I set /etc/system's zfs:zfs_arc_max = 0x1000 and it seems better now. I had previously tried setting it to 2Gb rather than 256Mb as above without success... I should have tried much lower! It "seems" that when I perform I/O though a WindowsXP hvm, I get a "reasonable" I/O rate, but I'm not

[zfs-discuss] Changing all the underlying device names...

Hi All, I'm a new ZFS convert (so far, I've only been impressed by ZFS) - I'm running it under FreeBSD 7 atm. I've got to 'shuffle' all the underlying devices around on my raidz pool - so their device names will all either change (e.g. "da0" will become "ad4") - or the devices will get 'jumbl

[zfs-discuss] Multiple ZFS partitions on overlapping region of USB stick

I used a usb stick, and the first time I used it, I used something similar to zpool create black c5t0d0p0 # ie with the "p0" pseudo partition and used it happily for some while. Some weeks later, I wanted to use the stick again, starting afresh, but this time used zpool create black c5t0d0 # ie

Intel show a configuration of this chassis in the Hardware Technical Specification: http://download.intel.com/support/motherboards/server/ssr212mc2/sb/ssr212mc2_tps_12.pdf without the RAID controller. I assume that then the 4xSAS ports on the Blackford chipset are then used, rather than the 4xS

Re: [zfs-discuss] ZFS write time performance question

The 250KB below was confusing to one reader. What I mean is that over the interval of the file write, it transfers 250KB of traffic. man iostat and you can see that it is correct. 250KB per second is not the bandwidth. I also understand the 'mkfile' is not an acceptable perrformance benchmar

No need to tune recordsize when the filesizes are small. Each file is stored as a single record. -r Le 29 nov. 07 à 08:20, Kam Lane a écrit : > I'm getting ready to test a thumper (500gig drives/ 16GB) as a > backup store for small (avg 2kb) encrypted text files. I'm > considering a zpool

So we have a zpool that was grown over time by using the 'zpool add' command to add some space. This has ended up with a zpool made of three devices on our old hp san. This is on solaris 10 sparc. I want to move the zpool to fc netapp storage using zpool replace, completely getting it off the H
