...in at a time. We need to be able to support 60-70 simultaneous calls initially and we have to be able to do this reliably. We also need to be able to scale into the 100's of simultanous calls range. What would be the best option, to have 2 powerful machines (dual powersupply, ) with one as a hotswappable backup or have multiple machines with a sort of load balancer setup? Having multiple machines could possibly cost less, but I'm not sure how the queues and agents would be managed across multiple machines. I.e. how would the agent 'login' to each asterisk machine so that the calls...

I tried it on loop. 1. mount /dev/loop0 /mnt/test -t ext3 2. cp files to 100% full 3. umount /mnt/test 4. fsck.ext3 -f /dev/loop0 Inode xxxxx, i_blocks is xxx, should be yyy. Fix?

Hi, I just came across this box [0] (McKay Creek). Seems to be exceptional building material for ZFS based NAS/iSCSI unit. I especially liked the two extra system disks hidden inside the box !
