Quota-enabled partition is 60 GB UFS2 containing 25,000+ customers' home directories with Maildir-style mailboxes and surviving 100,000+ deliveries (file creations) and approximately the same number of retrievals (file deletions) each day. mail:~# df -i /disk1 Filesystem 1K-blocks Used Avail Capacity iused ifree %iused Mounted on /dev/da1s1d 66343254 25904146 35131648 42% 1479119 7117359 17% /disk1 mail:~# mount /dev/da1s1d on /disk1 (ufs, local, noexec, nosuid, with quotas, soft-updates) If I can run some specific (stress?) tests that might provide useful information, let me know. Output of dmesg, vmstat, iostat, top, etc -- just ask. -- Aleksey
