Amanda has begun timing out one of my slower clients. I have tracked this down and it appears to be the fact that generating the estimates takes much, much longer now than it used to. Amanda estimates the amount of space a backup will take by actually starting the backup, waiting for the estimate line that follows the end of Pass II, then killing the backup. The problem is that for an unknown reason, Pass II is now taking an incredibly long time. For example: Filesystem 1K-blocks Used Avail Capacity iused ifree %iused Mounted on /dev/ad0s1e 1744767 1024514 580672 64% 167453 269025 38% /usr dial%df /usr Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/ad0s1e 1744767 1024514 580672 64% /usr Just getting the estimate line for a level 1 on this filesystem takes a half hour (CPU is a K6-233, disk is using UDMA33). Does this have something to do with the changes made to support hierarchical nodump processing? I have some trees on this fs that in the past I have done a chflags -R nodump on. Might this be causing dump some heartburn? To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
