The only process with files open for writing on /usr is squid, which is restricted to a 2gb cache_dir on a 7.5gb partition (this is to lower memory usage until we can add ram). Does anyone have any suggestions what to do? If the only answer is to run newfs it would be helpful to have some parameters to try (this fs was built with defaults). There are no options to the mount at the moment, the fs is using softupdates, and the disk is attached to a Symbios 895: da0 at ncr0 bus 0 target 0 lun 0 da0: <HP 9.10GB A 80-DC1B DC1B> Fixed Direct Access SCSI-2 device da0: 80.000MB/s transfers (40.000MHz, offset 15, 16bit), Tagged Queueing Enabled da0: 8678MB (17773524 512 byte sectors: 255H 63S/T 1106C) If any further information would help please let me know what would be useful. I guess the output from tunefs -p or dumpfs might help - I'll do this when I know whether there's anything else I need to do whilst the disk is unmounted.
