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 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 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).

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 a difference. I''m trying to understand why we''re seeing getting a lot of read requests to disk when the arc is s...

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
