Here's the tunefs -p output for one of the file systems: # tunefs -p /dev/da2.journal tunefs: ACLs: (-a) disabled tunefs: MAC multilabel: (-l) disabled tunefs: soft updates: (-n) disabled tunefs: gjournal: (-J) enabled tunefs: maximum blocks per file in a cylinder group: (-e) 2048 tunefs: average file size: (-f) 16384 tunefs: average number of files in a directory: (-s) 64 tunefs: minimum percentage of free space: (-m) 8% tunefs: optimization preference: (-o) time tunefs: volume label: (-L) I'm concerned about this because the ones I've had problems with recently are 1.1TB arrays...I've got 2 8.6TB arrays that are journaled as well...and if I ever have to fsck them...that could take 1/2 the day... Any other thoughts? Thanks for the help so far Ivan! --Brian
