We've been experience problems on treebase-dev which randomly forces the postgresql server offline. Looking through the logs, I see I/O errors which force the postgresql volume offline and then restarts it read-only. Postgresql cannot start on a read-only volume because it needs to right to logs and some temp space. I believe the problem arises from the current VM infrastructure. All VMs are using the same LUN to connect to the iSCSI storage repository. I've got a second repository not in use that contains faster SCSI disks than the SATA disks that we are currently using. I can also tune this new repository for faster I/O. So, in plain English, this means I'll be working on getting this new repository working and moving the postgresql volume to it. It should not take me more than an hour or two. I'll let you know when it's up and that should fix our postgresql issues. Sorry for the inconvenience. -Jon ------------------------------------------------------- Jon Auman Systems Administrator National Evolutionary Synthesis Center Duke University http:www.nescent.org jon...@ne... ------------------------------------------------------ |
