Ok, previous threads have lead me to believe that I want to make raidz vdevs [0] either 3, 5 or 9 disks in size [1]. Let''s say I have 8 disks. Do I want to create a zfs pool with a 5-disk vdev and a 3-disk vdev? Are there performance issues with mixing differently sized raidz vdevs in a pool? If there *is* a performance hit to mix like that, would it be greater or lesser than building

Has anyone here had any luck using a CF to SATA adapter? I''ve just tried an Addonics ADSACFW CF to SATA adaptor with an 8GB card that I wanted to use for a boot pool and even though the BIOS reports the disk, Solaris B95 (or the installer) doesn''t see it. I might give the IDE version a go (I really wanted hoT-plug), otherwise I''ll be able to store a couple of thousand

Anyone have any experience with a R510 with the PERC H200/H700 controller with ZFS? My perception is that Dell doesn''t play well with OpenSolaris. Thanks, Geoff

i have recently rebuilt dovecot on my mail server as i wanted to add SSL support for it. well, my OpenSSL libs are 64-bit, so what they hey, i'll build dovecot 64-bit as well. worked just fine, no issues at all. the setup is: Solaris 9/SPARC Sun C compiler Dovecot 0.99.14 after rebuilding it 64-bit, i now have a small problem however. I cannot save messages to IMAP folders from Mail.app

Hi gurus, I like zpool iostat and I like system monitoring, so I setup a script within sma to let me get the zpool iostat figures through snmp. The problem is that as zpool iostat is only run once for each snmp query, it always reports a static set of figures, like so: root at exodus:snmp # zpool iostat -v capacity operations bandwidth pool used avail read

Hi, ok I know zfs-fuse is still incomplete and performance has not been considered, but still, before I''m going to use it for my /home I wanted a rough estimate. Another benchmark already asserted that zfs by itself, on Solaris, is a very fast beast (http://cmynhier.blogspot.com/2006/05/zfs-benchmarking.html), faster than ext3 on Linux and also faster than UFS. Interestingly UFS seems

After the interesting revelations about the X2100 and it''s hot-swap abilities, what are the abilities of the X2200-M2''s disk subsystem, and is ZFS going to tickle any wierdness out of them? -brian -- "The reason I don''t use Gnome: every single other window manager I know of is very powerfully extensible, where you can switch actions to different mouse buttons.

Hi list, as this matter pops up every now and then in posts on this list I just want to clarify that the real performance of RaidZ (in its current implementation) is NOT anything that follows from raidz-style data efficient redundancy or the copy-on-write design used in ZFS. In a M-Way mirrored setup of N disks you get the write performance of the worst disk and a read performance that is

I''m putting together a NexentaOS (b65)-based server that has 4 500 GB drives on it. Currently it has two, set up as a ZFS mirror. I''m able to boot Nexenta from it, and it seems to work ok. But, as I''ve learned, the mirror is not properly redundant, and so I can''t just have a drive fail (when I pull one, the OS ends up hanging, and even if I replace it, I have to

Hi. I''m all set for doing performance comparsion between Solaris/ZFS and FreeBSD/ZFS. I spend last few weeks on FreeBSD/ZFS optimizations and I think I''m ready. The machine is 1xQuad-core DELL PowerEdge 1950, 2GB RAM, 15 x 74GB-FC-10K accesses via 2x2Gbit FC links. Unfortunately the links to disks are the bottleneck, so I''m going to use not more than 4 disks, probably.

With the release of the Nevada build 90 binaries, it is now possible to install SXCE directly onto a ZFS root filesystem, and also put ZFS swap onto a ZFS filesystem without worrying about having it deadlock. ZFS now also supports crash dumps! To install SXCE to a ZFS root, simply use the text-based installer, after choosing "Solaris Express" from the boot menu on the DVD. DVD download

ok, so, dovecot 0.99.11, Solaris 9. i have: auth_userdb = passwd auth_passdb = shadow in my dovecot.conf, which gets me logged into dovecot in the first place, but then i get: Sep 9 09:52:41 ford.4amlunch.net imap-login: [ID 457029 mail.info] Internal login failure: wonko [10.0.1.6] in /var/log/syslog how do i track down exactly what the problem is so i can fix it? i would love to add SSL

i don't know what happened, but it just started giving me better errors. i had to set first_valid_uid=100 since that's where my users start. wow, dovecot is FAST. -brian -- "The cats tend to administer themselves, and contrary to the expected facts, the house and everything in it was installed for their benefit." -- Nic Clews

i'd *really* like to get to maildir. so here it is, one last time.... using 0.99.x, can i have an mbox spool file and Maildir folders? for just one account? if i can do that, then it'll be a lot easier to transition the whole mess to Maildir. i use procmail called from postfix to deliver mail. is that going to be an issue for delivery? if i don't set DEFAULT and just change all

I've got Sun's Directory Server 5.2 installed here, and I would like to have dovecot use it for virtual users. I have the following questions: a) How do I get dovecot to link to DS's libraries? Am I better off just building OpenLDAP client libraries and linking dovecot with them instead? b) how about password-hash {CRYPT} in the OpenLDAP config file? Do I need to do anything to make

I''d love to be able to server zvols out as SCSI or FC targets. Are there any plans to add this to ZFS?
