I wrote a small perl script to check and got the following results: doorway:~/proj/dumpsize> sudo ./dumpsize.pl /export /var/dumps/export9-part1 Level 9 dump of /export on doorway.home.lan:/dev/ad0s1h Label: none The level 0 dump of /export partition written to /var/dumps/export9-part1 contains 717 files totalling 28006 KB, cf size of dumpfile = 0 ( 104660 ) doorway:~/proj/dumpsize> ll /var/dumps/export9-part1 -rw-r--r-- 1 root wheel 107171840 Nov 25 05:13 /var/dumps/export9-part1 The size of the dumped files totals 28 MB whilst the dump file is 105MB. Any ideas as to what the rest of the file contains? >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
