I'm still not understanding what you want or what the problem is. This appears to me to be a perfectly ordinary mounting situation. If you have a bunch of dirs, data[1-2], as subdirectories of /stuff, then you can put whatever you want in these. Then, at some point you can mount a different volume on any of these and the path will remain as /stuff/datax. If you wish to then change the mounted volume, just change your fstab or mount command as appropriate. This will work with samba and nfs, as long as your smb.conf and exports are set up correctly, and is a perfectly ordinary situation, as I said. I'm confused by: I want a mounting point in the root file system to be mounted with a directory found inside a device that is not yet mounted. Do you want to hierarchically mount filesystems?

From: "bofh" I have to ask - if you're not copying the code, but only copying the concept/technical requirements over (ie, a rewrite), that new code would be bsd licensed, right? Probably, but this is filesystem code. The last thing you want to do is to replace complex, generally well debugged code with new complex not so well debugged code!

not

I'm sure they will correct me if I'm mistaken. The ZFS code is under a license which the OpenBSD team have deemed incompatible with the BSD License they use. [0] Whilst there could be a FUSE-based implementation of ZFS on OpenBSD, and indeed I think one may have already been started, to properly take advantage of the strength of ZFS the code would have to be in the kernel.

About the same as porting anything substantial to OpenBSD. The developer must be passionate about the project and have the resources (time, money) to accomplish it[1]. There is no way to quantify the odds of this happening. I see no code attached to your email, so I presume you're not volunteering.

Mount directories of unmounted disks/partitions
Hello all! I have an issue with mount. The problem is that i would like to create a directory with subdirs. On the subdirs I would mount directories of not yet mounted disks. Example mount /stuff/data1 /wd0d/dataa mount /stuff/data2 /wd0d/datab mount /stuff/data3 /wd1d mount /stuff/data4 /wd2d/datad mount /stuff/data5 /wd2d/datae I want to do this because datax are all growing fast (it is my music and photos). Eventually dataa and datab will need their own disks. Can this be done in a neat way? I only want to mount disks on the root partition <> The d00...@dtek.chalmers.se email address will eventually be abandoned during 2009.

You should really take these questions to an awk forum, not to this
mailing list.
Your program reads the first record, and assigns its first column to
'n' in a loop that is immediately exited (with 'next') and goes on to
read the remaining records.
For the remaining records, 'i' being still 1 from the prematurely
exited loop, the first column is subtracted from 'n'.

Are you expecting '0' since the input file contains a space in front
of the number? In that case, run awk with "-F '[ ]'", e.g.
awk -F '[ ]' '{sum+=$1} END {print sum}' input

Capturing useful debugging info on a hung machine (T1000)
I have a Sun Fire T1000 (sparc64), which a while ago was occasionally panicking, and I submitted a bug. kettenis@ commited a fix, and it stopped panicking. All good. Now I have a different problem. Every now and then, it just hangs. As far as I can tell, its a complete hardlock. I can't get it to go to ddb, I can't ping the box, it just sits there. I've been running screen on a machine connected to the serial console, running while true; do uptime; sleep 5; done for the past few days, and it seems that when it hangs, it does so whilst updating the various mirrors the box hosts, at around 3am. I suspect this is more to do with load than the specific task. My question is this: Is there anything I can do to gather useful information? At the moment all I have is a dmesg and "It hangs sometimes under load." which is bugger all use to anyone. Is there a magic key sequence I can send to the serial console? Is there a sysctl I can turn on? Is there a ukc or config knob I can poke? I don't mind running with crazy debug symbols or silly cronjobs that chuck debug data to disk once a minute, I just want to be able to put something helpful in sendbug(1).

httpd startup: Syntax error on line 1 of /var/www/conf/modules/php5.conf
Hi All! Starting httpd returns: Syntax error on line 1 of /var/www/conf/modules/php5.conf Cannot load /usr/local/lib/php/libphp5.so into server: Cannot load specified object Before I added the php packages httpd started fine. (And mysql works perfectly too.) I did what seemed to be a fairly intuitive php install with no research, and got the error. Then I find a FAQ page at openbsd.org that says the same thing. Then I find a web page with the same details describing a typical 'OAMP.' They're all about the same, a few pkg_add and ln -s no real 'work' to this. BTW this is a virgin new 4.4 install not an upgrade. I've also been to ~/patch and installed those and recompiled the kernel and httpd -after- the first faulty starts, with still the same error both before and after the patches. I see one long discussion at http://kerneltrap.org/mailarchive/openbsd-misc/2008/11/17/4139684/thread but at the end there's no definitive answer as to what caused it or if/how it was fixed. From which I tried 'old version check.' cat /var/www/conf/httpd.conf | grep 'LoadModule php' returns empty And httpd -u returns the same error CLI seems to work fine. Logs. Between good httpd starts without, and bad ones with php enabled, I 'zero-lengthed' the logs to make -sure- if I was seeing something 'new.' but failed starts produce nothing at all /var/www/logs. I tried php.ini display_startup_errors but that produced nothing either. I also touched /var/www/logs/php.log because there wasn't one but that made no difference. These -look- normal: # cat /var/www/conf/modules/php5.conf LoadModule php5_module /usr/local/lib/php/libphp5.so AddType application/x-httpd-php .php .phtml .php3 AddType application/x-httpd-php-source .phps # Most php configs require this DirectoryIndex index.php # ls -l /usr/local/lib/php/libphp5.so -r--r--r-- 1 root bin 3968192 Aug 12 14:07 /usr/local/lib/php/libphp5.so # ll /var/www/conf/modules lrwxr-xr-x 1 root daemon 29 Jan 15 03:18 libphp5.so@ -> /usr/local/lib/php/libphp5.so lrwxr-xr-x 1 root daemon 18 Jan 15 03:18 php@ -> /usr/local/lib/php lrwxr-xr-x 1 root daemon 38 Jan 14 17:00 php5.conf@ -> /var/www/conf/modules.sample/php5.conf I 'commented out the contents' of php5.conf causing it to load nothing, and httpd started fine. I did a complete pkg_delete of everything php related, and httpd started fine. Reinstalled and got the same error. Maybe I've got a wrong permission or ownership? I wish they'd add to the doc pages an ls -l for the installed subdirs just for completeness. Weird all around. TIA. Have a :) day! Jim -- jim barchuk j...@jbarchuk.com
