Re: [zfs-discuss] Oracle DB sequential dump questions

I would look at what size IOs you are doing in each case. I have been playing with a T5240 and got 400Mb/s read and 200Mb/s write speeds with iozone throughput tests on a 6 disk mirror pool, so the box and ZFS can certainly push data around - but that was using 128k blocks. You mention the

[zfs-discuss] query: why does zfs boot in 10/08 not support flash archive jumpstart

2008-10-01 Thread Adrian Saul
With much excitement I have been reading the new features coming into Solaris 10 in 10/08 and am eager to start playing with zfs root. However one thing which struck me as strange and somewhat annoying is that it appears in the FAQs and documentation that its not possible to do a ZFS root

[zfs-discuss] ZFS error handling - suggestion

2008-02-18 Thread Adrian Saul
Howdy, I have at several times had issues with consumer grade PC hardware and ZFS not getting along. The problem is not the disks but the fact I dont have ECC and end to end checking on the datapath. What is happening is that random memory errors and bit flips are written out to disk and

[zfs-discuss] suggestion: directory promotion to filesystem

2007-02-21 Thread Adrian Saul
Not sure how technically feasible it is, but something I thought of while shuffling some files around my home server. My poor understanding of ZFS internals is that the entire pool is effectivly a tree structure, with nodes either being data or metadata. Given that, couldnt ZFS just change a

[zfs-discuss] Re: pools are zfs file systems?

2006-07-15 Thread Adrian Saul
when playing with ZFS to try and come up with some standards for using it in our environment I also disliked having the pool directory mounted when my intentions were not to us it, but subdivide the space with in it. Simple fix: zpool create data blah zfs create data/share zfs create

[zfs-discuss] S10U2: zfs instant hang with dovecot imap server using mmap

2006-07-14 Thread Adrian Saul
Hi, I just upgraded my home box to run Solaris 10 6/06 and converted my previous filesytems over to ZFS, including /var/mail. Previously on S10 FCS I was running dovecot mail server from blastwave.org without issue. On upgrading to Update 2 I have found that the mail server hangs
