With the addition of journalizing file systems, the time cost of fsck certainly has been reduced. For the most part, especially for laptops, many people just use 1 or 2 partitions. In the olden days, we would segment our partitions as you mentioned above, for backup and other purposes. And, with todays large drives, if you want a finer granularity, LVM can serve you well because of its ease in being resized. Basically, the right way to partition a system depends much on how it is going to be used. Certainly, the system data (/etc,/dev/,/bin,/sbin,/usr...) is very stable, and you read from it mostly. /var is a good candidate for a separate partition because it contains a lot of volatile data (as does /tmp). /home is also a good candidate to be in its own partition. But, in the olden days we used to use the Unix dump(8) to back up by file system, but today we have a lot of good backup alternatives. -- Jerry Feldman Boston Linux and Unix PGP key id: 537C5846 PGP Key fingerprint: 3D1B 8377 A3C0 A5F2 ECBB CA3B 4607 4319 537C 5846 signature.asc Description: OpenPGP digital signature ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

If that's your concern, the utility should have an output mode that's more friendly to machine interpretation. :) But frankly, for something like mount statistics, it's not worth worrying about efficiency, and parsing isn't complicated enough to worry about errors. An API is an API, regardless of whether it's a C struct via ioctl() or text output from e2fsck. If nothing changes, both work equally well, and if things change, the later handles change much better. :) You just think the C struct way works better because when that changes, your program just segfaults when it's doing something completely different, so you never learn why. The text method fails gracefully, and you actually have a chance of diagnosing it and fixing it. :) And it's not like /proc or /sys *aren't* giving you text output. :) Unix is built on a bunch of small, independent utilities exchanging text data. Among other things, that builds an easily diagnosed system, and one which handles change gracefully. :) > I'd have guessed this would be exposed in sysfs ... Just as bad as sticking it in /proc.

>I also think it would be neat to have the gathering on the anniversary >date. Well, to throw a little gasoline into the discussion: o The date you mention is the date of the first meeting of what-would-become the GNHLUG meeting. I still remember sitting around a few weeks later trying to discuss what the name would actually be, and coming up with a name that (hopefully) would attract people from the "Greater" New Hampshire area (including Northern Mass, Maine and Vermont). More importantly, the name sounded like "someone drinking a mouthful of homebrew." So a little like "Independence Day" in the United States, while most people might think it is "July 4th", the actual development stretches it over a longer period of time. o The date you mention was, I believe, the first and last meeting that Bob hosted/led. After that he explained that he was too busy and did not have time for it, so I took over for a rather lengthy time. Just to show that moving it a few days in one direction or another might not make much difference when averaged out over the last 15 years. md ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

I should probabbly mention that when I wrote "partition" I actually meant "logical volume". I used to do it with simple partitions, which worked, but the occasional move/resize for reallocation required taking everything offline, and waiting while that happened. These days, I use LVM, and put everything other than the boot partition in LVs. I leave free space in the volume group. Growing an LV and the filesystem inside it only takes a few moments. It works well. As another example, on the GNHLUG Internet server, I've got several different LVs for each task. For example, logs get their own LV, as does the mail spool. This keeps runway process output (or DoS attacks) from filling up the entire system. A full root partition will often wedge everything, but a full mail spool just knocks out mail. Then you can SSH in and fix it. -- Ben ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

I see the question's been answered, but here's some general commentary, FWIW. I generally find it's more appropriate to use the time interval check, and disable the maximum mount count check. The theory being that it doesn't really matter how often you mount the filesystem. If you reboot 5 times a day because you shut your PC off when you're not using, that doesn't necessarily mean you need to check every week. Contrariwise, if you almost never reboot, that doesn't mean you only need to check once per decade. Since I like to divide things up into multiple partitions, I can also tune based on filesystem usage. For example, my /tmp partition checks every 30 days, but my /usr partition checks every 180 days The theory being that a filesystem with more activity is more likely to encounter problems. I have my root and boot partitions set to check every mount. The theory being that they're really important. They're also small in my setup, so it only takes a few seconds. OTOH, if you have multiple partitions, you can disable the time interval and use different mount counts, and avoid checking multiple filesystems at once. -- Ben ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
Re: [GNHLUG] GNHLUG is turning 15! Let's have a party!
Well, I'll be with you in spirit, and will lift a frosty mug that evening to celebrate. I'm currently spending the summer in Hendersonville, NC, where we have a second home, and run openSUSE 11.1 on the second hard drive on my HP dv9000z laptop. I also have a 320GB USB drive with F11, openSUSE 11.2, Karmic Koala, my backups, and a free partition for another distro. So, I'm keeping my hand in, playing with the latest-n-greatest, as well as looking into various amateur radio applications, particularly those used for emergency situations (Amateur Radio Emergency Service),and trying to evangelize Linux amongs my fellow hams, both here in the WNC mountains (which are very reminiscent of central NH) and down in south Florida where we live when it's not hurricane season. I hope someone can find Bob Curry, KC1IB, possibly through the ARRL mail forwarder or some other means, and invite him to the celebration, as well as Gary Grebus and whomever else was there that night. Wow, 15 years - I'm still shaking my head because I remember it like it was yesterday. My thanks to all of you for carrying it forward so well!

What do others think? I eat eat every day (so far) and any excuse for a party is a good excuse. My preferences are low to moderate price and quiet. Any day has an equal probability of good or bad right now - bad being a smaller probability. If it is on a Wednesday, I can bring my wife along too. Does Blake's in the north end have a function room? Oops! That would mean no booze, the lack of which might be important to some.

Insert creative ramblings here about how btrfs will allow on-line fsck's, include per-file checksums, and wash your dishes.

How can I retrieve the mount count for an ext3 volume?
My Ubuntu 8.10 system uses EXT3 for the root filesystem and will automatically fschk the volume every 35 mounts. I haven't been able to find out where the mount count is stored or how that data can be retrieved. I don't want to change the automated fschk but I'd like to display the count so I can anticipate when the volume will be checked. -Alex ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

As long as the place serves picky eaters like me* I'll be there.
