I needed to expand a /var partition,
which required saving and restoring /var and /usr
did the following:
booted to backup disk
dump -0aR -h 0 -f /usr/backup/dump_var_0_20121113_1920 /dev/ada0p4
(repeat for /tmp, /usr, / partitions to be safe)
repartitioned the main disk using gpart
newfs the modified partitions (var, tmp, usr)
rewrote the boot block and boot partition (#1)
mount /dev/ada0p4 /mnt/ssd/var
cd /mnt/ssd/var
restore -r /usr/backup/dump_var_0_20121113_1920
Cannot find file dump list
Any ideas why I get the "Cannot find file dump list"?
What / where is it supposed to be?
I was able to get some stuff back from one of the files,
but only by doing:
#restore -if /usr/backup/dump_usr_0_201121113_1920
restore > verbose
restore > add libdata
restore > extract
Extract requested files
You have not read any tapes yet
If you are extracting just a few files, start with the last volume
and work towards the first; restore can quickly skip tapes that
have no further files to extract. Otherwise, begin with volume 1.
Specify next volume #: 1
Mount tape volume 1
Enter "none" if there are no more tapes
otherwise enter tape name (default: /usr/backup/dump_usr_0_20121113_1920)
unknown tape header type -2
abort [yn] n
resync restore, skipped 786 blocks
extract file ...
...
Add links
Set directory mode, owner, and times.
Set owner / mode for '.' [yn] y
restore >
If I did not enter <Enter> after the "otherwise enter tape name",
but rather entered "none"
I did not get all of the desired contents.
Can anyone shed light on this problem?
I have been able to restore most everything from a cp I had done
at the same time, but I'm not very confident in the results.
Fortunately, user data was on a different disk.
Obviously, should have done a
restore -rN ...
before repartitioning. Ugh.
Related question:
I now realize I should not have answered "y" to the set owner / mode
question, as it changed the mode to the default for root instead of
doing what I thought which was restoring the owner / mode to what was
saved in the dump. Will
restore -x /usr/backup/dump...
correct the owner and mode? (and group and flags?)
Thanks,
Gary
