Hey all - Was playing a little with zfs today and noticed that when I was untarring a 2.5gb archive both from and onto the same spindle in my laptop, I noticed that the bytes red and written over time was seesawing between approximately 23MB/s and 0MB/s. It seemed like we read and read and read till we were all full up, then wrote until we were empty, and so the cycle went. Now: as it happens,

Hi, I''m running Opensolaris 2009.06, and I''m facing a serious performance loss with ZFS ! It''s a raidz1 pool, made of 4 x 1TB SATA disks : zfs_raid ONLINE 0 0 0 raidz1 ONLINE 0 0 0 c7t2d0 ONLINE 0 0 0 c7t3d0 ONLINE 0 0 0 c7t4d0 ONLINE 0 0

I have the need to maintain a pseudo-realtime database of active calls across a number of asterisk servers. The main purpose of this is in determining where to route calls (e.g. don't send calls to a server with no free lines) and also for monitoring/recirding calls. I know that astguiclient does this by telnetting into the * server management interface ever 333ms and updating a MYSQL

I have spent a while trying to join a samba machine to our university's active directory structure so that allowed users can map to it by simply running \\webserver I was able to join the machine just fine via: net ads join VPSA/UH/UH-_ResComp_Servers/ -U adminname And now I can run wbinfo -u to get a listing of all users on our network. I have the right permissions, because from that

Hi, I hope there''s someone here who can possibly provide some assistance. I''ve had this read problem now for the past 2 months and just can''t get to the bottom of it. I have a home snv_111b server, with a zfs raid pool (4 x Samsung 750GB SATA drives). The motherboard is a ASUS M2N68-CM (4 SATA ports) with an Athlon LE1620 single core CPU and 4GB of RAM. I am using it

Hi all, just after sending a message to sunmanagers I realized that my question should rather have gone here. So sunmanagers please excus ethe double post: I have inherited a X4140 (8 SAS slots) and have just setup the system with Solaris 10 09. I first setup the system on a mirrored pool over the first two disks pool: rpool state: ONLINE scrub: none requested config: NAME

I have historically noticed that in ZFS, when ever there is a heavy writer to a pool via NFS, the reads can held back (basically paused). An example is a RAID10 pool of 6 disks, whereby a directory of files including some large 100+MB in size being written can cause other clients over NFS to pause for seconds (5-30 or so). This on B70 bits. I''ve gotten used to this behavior over NFS, but

I was trying to simply test bandwidth that Solaris/ZFS (Nevada b63) can deliver from a drive, and doing this: dd if=(raw disk) of=/dev/null gives me around 80MB/s, while dd if=(file on ZFS) of=/dev/null gives me only 35MB/s!?. I am getting basically the same result whether it is single zfs drive, mirror or a stripe (I am testing with two Seagate 7200.10 320G drives hanging off the same interface

We have a zpool made of 4 512g iscsi luns located on a network appliance. We are seeing poor read performance from the zfs pool. The release of solaris we are using is: Solaris 10 10/09 s10s_u8wos_08a SPARC The server itself is a T2000 I was wondering how we can tell if the zfs_vdev_max_pending setting is impeding read performance of the zfs pool? (The pool consists of lots of small files).

Hello, I use Brendan''s sysperfstat script to see the overall system performance and found the the disk utilization is over 100: 15:51:38 14.52 15.01 200.00 24.42 0.00 0.00 83.53 0.00 15:51:42 11.37 15.01 200.00 25.48 0.00 0.00 88.43 0.00 ------ Utilisation ------ ------ Saturation ------ Time %CPU %Mem %Disk %Net CPU Mem

Hi! I have a problem with ZFS and most likely the SATA PCI-X controllers. I run opensolaris 2008.11 snv_98 and my hardware is Sun Netra x4200 M2 with 3 SIL3124 PCI-X with 4 eSATA ports each connected to 3 1U diskchassis which each hold 4 SATA disks manufactured by Seagate model ES.2 (500 and 750) for a total of 12 disks. Every disk has its own eSATA cable connected to the ports on the PCI-X

I figure this group will know better than any other I have contact with, is 700-800 I/Ops reasonable for a 7200 RPM SATA drive (1 TB Sun badged Seagate ST31000N in a J4400) ? I have a resilver running and am seeing about 700-800 writes/sec. on the hot spare as it resilvers. There is no other I/O activity on this box, as this is a remote replication target for production data. I have a the

I have a CentOS 3.8 server which i manage for web hosting (web server, mail server + database server). Today i got it down because of an attack, here is the last snapshot of top command before server dies 09:47:30 up 21 days, 6:54, 1 user, load average: 363.88, 727.82, 253.42 3949 processes: 135 sleeping, 3800 running, 14 zombie, 0 stopped CPU states: cpu user nice system irq

Pre-fletching on the file and device level has been disabled yielding good results so far. We''ve lowered the number of concurrent ios from 35 to 1 causing the service times to go even lower (1 -> 8ms) but inflating actv (.4 -> 2ms). I''ve followed your recommendation in setting primarycache to metadata. I''ll have to check with our tester in the morning if it made

Hi. T2000 1.2GHz 8-core, 32GB RAM, S10U3, zil_disable=1. Command ''zpool export f3-2'' is hung for 30 minutes now and still is going. Nothing else is running on the server.

I have a system that is running into problems with high load, however, even when I shut down everything that could be loading the system, the load continues to rise. I can't see anything that is causing the load.

We''re running a Cyrus IMAP server on a T2000 under Solaris 10 with about 1 TB of mailboxes on ZFS filesystems. Recently, when under load, we''ve had incidents where IMAP operations became very slow. The general symptoms are that the number of imapd, pop3d, and lmtpd processes increases, the CPU load average increases, but the ZFS I/O bandwidth decreases. At the same time, ZFS

I've got the latest asterisk 1.8 running on a Netra X1 with Solaris 10 u10. The system itself is happy and phone calls (between two parties) seem fine. Unfortunately, when a caller listens to a Playback recording, there seems to be moments of stutter - perhaps 1 second of stutter for every 10 seconds of Playback. The stutter is not consistent at the same point of the playback file. To
