I'm almost sure it is, but just want to make certain. Um... it's probably OK, but you're really the only person in a position to know, given it's your system. Given that you have been actively maintaining your systems using pkgng for several months, the pkg.bak file will not contain any record of the changes made in that time.

Admittedly disk space is cheap, but old habits die hard and I just don't like keeping stuff I no longer need. I converted to pkgng just under a couple of months ago, and have had no serious problems (even the minor issues have been promptly resolved with the kind and able assistance of Matthew Seaman). I have no intention of trying to 'go back', so my question is this: Is it safe now to clear out the pkg.bak file which was created by pkg2ng at the time of conversion? I'm almost sure it is, but just want to make certain. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

I assumed it was because the system was very old and I was upgrading from 7.0 to 9.1, although I tried in every step to upgrade the ports and failed (i.e. 7.1, 8.1, 8.2, 9.1). I wound up pkg_delete -a -f . I was going to re-install everything in Jails anyway so I was happy to delete all ports from the base sys. I can say however that the upgrade from 7.0-RELEASE to 9.1-RELEASE went very smoothly with freebsd-update, but as I mentioned above, I did it in steps.

The fix to your issue is, in pseudocode: for part in ( OS , ports ) do: determine owner rocketmouse:* for all files compare with list with correct owner for each deviating file do: if owner != correct owner then: chown file to correct user fi od od Of course OS and ports have to be treated seperately. As you have mentioned to own a backup where the permissions (owners) are correct, obtaining the required reference data from that backup would be the easiest part. The alternative: reinstall world, reinstall ports.

Files are usually installed to the system by the "install" command, and it is employed in the Makefiles for the OS and also for ports. As you correctly recognized, not simply all files belong to root, so everything "non-standard" could be derived from such "control files". Of course, the more files you have to treat (see wc -l of your result list), the harder the task can become, and maybe installing the port again is faster than finding out where permissions are set for the install program call. If you only have 10 files or so, do it manually, but if there are 100 and more files, coming from several different ports, reinstalling them sounds easier, and it's not a big deal to do that with portmaster. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

A thing regarding awk: For extended formatting, use the
printf() command which works the same as in sh and C, os
if you need, you can do things like
printf "%s '%s'", $1, $2;
Also note that you can have a custom delimiter for parsing
the input, e. g. -F ":" (if you would generate input lists
in :-separated CSV format).
Additionally, it seems you're running into the fun of spaces
in file names. Even though you can put them there, it doesn't
imply it's good to do it. Spaces are separators (for commands
and options), and everytime they're _not_ (e. g. when they
appear in file names), you need to care for this fact, by
escaping or quoting them.
Maybe those articles by David A. Wheeler are interesting
to you to learn about this annoyance for people writing
short shell scripts to automate tasks:

Re: How to fix a broken owner for files from world & build from ports?
I suspect it's less effort to use Thunar and instead of scrolling, as I
did before (when I missed some wrong owners), to switch sorting by owner
between ascending and descending, to ensure not to miss a bad owner again.
I'm surprised, there's no /bin/sh for the backup:
/bin
# find /usr/TMP4DIFF/bin -ls | sed -e 's%/dir%%g' | awk '{print $5" "$11"
"$12" "$13}' > bin.TMP.txt
# find /bin -ls | sed -e 's%/dir%%g' | awk '{print $5" "$11" "$12" "$13}'
bin.BSD.txt
# diff bin.TMP.txt bin.BSD.txt > bin.DIF.txt
# grep rocketmouse bin.DIF.txt
rocketmouse /bin/sh
# ls -ld /bin/sh
-r-xr-xr-x 1 rocketmouse wheel 142952 Dec 23 18:38 /bin/sh
# ls -ld /usr/TMP4DIFF/bin/sh
ls: /usr/TMP4DIFF/bin/sh: No such file or directory
/lib
[snip ... no differences]
I anyway will unpack /usr too and take a look at the directories from the
backup. I won't bother you with each detail, but report a list of
differences, if there should be something very strange.

Ralf

Writes will be just as if you are writing to 1 drive, reads will be faster.

You can't use the gmirror remove directive when a drive has failed, but you do a gmirror forget , swap it, then just do gmirror insert to insert the replaced drive into the mirror. When everything is working as it should gmirror is mostly 'automatic', e.g. after the insert the rebuild just starts. Main thing I appreciated about this is the server stayed up and online after one drive died. My two servers at home are my testbeds to test out things first before doing stuff to the ones at work. I just installed both to 9.1. The difference now is I've used GPT (gpart) and this is new to me. Previously everything was always fdisk and disklabel. Both these machines are setup on one drive at this point and I haven't yet gotten into the mirroring yet. With the old fdisk/disklabel it was simple to just mirror the entire drive itself (slice). The other approach is to mirror partitions. I think I may need to do this as I think this is the way you have to proceed in order to avoid having gpt and gmirror both trying to claim the last sector on the drive (metadata storage). -Mike ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

The disks are all the same type, and I formatted them for FreeBSD and put ZFS in a slice covering most of them.

Responses from Vladimir Kostyrko ^ : ^ My home computer is set up in the dedicated mode. No grave difference. ^ Not even a scratch. Does this apply to FreeBSD and ZFS too? ^ No. Presumably the disks are currently FreeBSD-specific.

In general, I find all this thread (wrong file owner) a bit boring. This
is a mayor damage and can only be repaired by a new installation. A lot
of files and directories in the systems filesystem, in / /var /usr, have
dedicated owner to allow certain processes which does not run as 'root'
to do their correct work there, for exmample 'mail'; i.e. you can not
do just a complete "chown -R root " and expect that the system
still works;
the same is true for the ports below /usr/local; just run on a correct
system something like:
# find /usr/local -exec ls -ld {} \; | fgrep -v root
to get a list about what I am talking.
