Depends whether a remount-read-only flushes out the 'file system clean' bit when it's done at this level, or whether the change waits for the next sync, which is presumably the concern. Aiui a normal remount/umount wouldn't return until the flush is complete, but this method is far from normal.

Well, sod you. These CLUG people seem to have an aversion to trimming quotes and their mailserver is still not accepting my subscription request, so maybe they deserve to be held. :^) Seriously, there are reasons why the ALUG lists are set up in the way they are. Bitter experience is one of them and I think the issues around them have been talked to death on-list, so the archives might make interesting searching. > When a friendly human admin has time to moderate, that's bearable. I don't > object to moderated lists, when there is a good reason to use that approach. This list is not moderated, but posts by unknown addresses and ones which match certain other common features of past spams are held for one of the (currently three) list admins to take a look at before they are allowed through. > I was told that the CLUG listserver maintainer is long gone, however.

Indeed. Our areas overlap and I always hoped our activities would overlap at some point. It's nice to see it starting to happen. -- MJR

Might I suggest that we set up a joint mailing list for techie discussions, and then have separate ones for clug/alug meetings and other geographically-based discussions? -- Ian (who keeps getting 'message moderated' messages from the alug list)

"VM: do_try_to_free_pages failed for nmbd"

This lovely message was waiting to greet me on all consoles of my debian box when i came in to work this morning, and I can't telnet in. A search on google says: >Upgrade to 2.2.19 , that should fix the problem. It's a bug in the >releases between 2.2.14 and 2.2.19, afaik. Has anyone heard of this before? I'm using kernel 2.2.18pre 21, activity on box over weekend should have been minimal apart from backups running. And what were those keys that try to reboot cleanly again? (not the ctl-alt-del) (Hope it isn't going to be one of "those" days....) Nice to meet so many folk yesterday. Jenny.

It's also not there by default in Redhats to 7.1 (not tried 7.2), although RH-default kernels have sysrq compiled in. Strange. Dunno whether there's a nice way of turning it on; we just bodged up an init script for it.

RedHat7.2 memory shortage?
by Glen Tyler 05 Nov '01

05 Nov '01

Hi everyone, I'm just starting migration, and was impressed enough with what I'd seen of an old copy of RedHat 6.0 to install RedHat 7.2 on my machine. Its a P133 with 64MB, and 4.0GB hard drive. While I'm impressed with all the eversocool features of this (desktop) install, it has slowed the system to a crawl. Everything seems to take ages to load and respond, and trying to do anything more than just move the mouse about or type in Kword seems to involve a huge amount of thrashing of the hard disc (the swap space being utilised?). I've noticed that balsa as and email client and Galeon as a web browser seem faster than Mozilla - is there a suite of 'lighter' programs that I should choose? Any recommendations? Glen

That would make sense - nmbd would have been trying to allow NTserver to access the linux box to copy my backup file to its backup tape. But my backup file was getting its proverbial knickers in a twist. Thanks all. Jenny.

Stupid thing to do, but even more stupid as it is the 2nd time I've done that. Some people *never* learn....... ;-) Jenny.
