I hope everyone enjoyed their foods & drinks during Christmas:) Now, being new to 10-RELEASE, things continue to amaze me, but I attribute that to my slowness in understanding 10. I have been used to 8.x and below so much that when changes started getting into 9.x and into 10.x I was simply overwhelmed. Now it's biting. I have a server I installed with two identical disks. I used BSD labels instead of GPT and I had it a little rough creating my slices, because I am used to a situation where I only created / amd swap for such servers because it made life easy for me during backup. I would completely wipe all data on the second disk every Saturday, via a cron, and write it with data from the primary/running/active disk as a means of backup. Not so dandy but works quite fine anyway. Now I have gotten to a point where I am stopped in my tracks because I cannot do dump/restore on a journaled fs: root@mail:/ # mount /dev/ada0a on / (ufs, local, journaled soft-updates) devfs on /dev (devfs, local, multilabel) /dev/ada1a on /disk2 (ufs, local, journaled soft-updates) fdescfs on /dev/fd (fdescfs) root@mail:/ # df -h Filesystem Size Used Avail Capacity Mounted on /dev/ada0a 446G 6.5G 403G 2% / devfs 1.0K 1.0K 0B 100% /dev /dev/ada1a 446G 32M 410G 0% /disk2 fdescfs 1.0K 1.0K 0B 100% /dev/fd root@mail:/ # ls -al /disk2/ total 32840 drwxr-xr-x 3 root wheel 32768 Dec 22 16:28 . drwxr-xr-x 20 root wheel 1024 Dec 26 16:30 .. drwxrwxr-x 2 root operator 512 Dec 22 16:28 .snap -r-------- 1 root wheel 33554432 Dec 22 16:28 .sujournal root@mail:/ # grep dump /scripts/backup_primary_disk.sh /sbin/dump -L0af - / | (cd /disk2/; restore -rf - ) root@mail:/ # /sbin/dump -L0af - / | (cd /disk2/; restore -rf -) mksnap_ffs: Cannot create snapshot //.snap/dump_snapshot: /: Snapshots are not yet supported when running with journaled soft updates: Operation not supported dump: Cannot create //.snap/dump_snapshot: No such file or directory Tape is not a dump tape root@mail:/ # So, do I have to disable the journaling option from the FS, or is there a better way to achieve the same result with journaling still on? -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 "I can't hear you -- I'm using the scrambler."
