Server crash - is recovery possible?

by Richard Goodman

I'm running a RH 7.0 box at home that does (a) NAT for the local network (b) mail server for multiple domains (c) web server for multiple domains and (d) DNS for multiple domains Yesterday I attempted to ssh login from a workstation and got a message "..exited with Signal 11". I attempted to log on from the console and could not - got screen full of messages and numbers. At this point at least the web server was still running. I hit reset to reboot, got all the standard messages until "Checking root filesystem...." About 5-10% in, then: "Warning ..fsck.ext2 for device /dev/hda2 exited with signal 11 [FAILED] " Looked in my configuration book this morning ... hda2 is "/" . The only fortunate thing is that /home and /var are separate partitions on a second hard drive. Is there any way to recover from this? Barring that - is there any way to recover any config files from various places in /etc on this partition. If not I guess its a complete reload - mainly a problem with mail and DNS config files. I am only mildly competent on this stuff. If you need more info, I'll get it, although I don't know how to capture that screen full of info at the abort point.

when helping people solve their alsa problems, the answer almost always was 'use kernel drivers' as soon as they did, their problems went away -mike ----- Original Message ----- From: "Keith Wright" <kwright(a)gis.net> To: <wlug(a)mail.wlug.org> Sent: Sunday, August 25, 2002 16:54 Subject: Re: [Wlug] /dev/sequencer problems > > From: "Michael Frysinger" <vapier(a)WPI.EDU> > > > > If you're alsa or something, g'luck, cause i'm not touching alsa ;) > > Why is this?

Is it personal (e.g. you have no time for it), or kwright> is there something I should know before I start touching ALSA? As to the last question: It certainly is a bit trickier to set up, but that is mainly because it isn't integrated into most distributions or mainline stable kernels. However, now that Linus has accepted it in kernel 2.5, we will hopefully see more support built-in to the distributions. Once you set it up, however, it has more advanced features. Your applications would need to be coded to the native ALSA API to take advantage of most features, but there are some other neat things you can do without specific application support, like intercept the output stream for visual effects and/or recording. Major apps like XMMS (via external plugin), xine and mplayer have ALSA support. My main impetus for using it is that the i810 AC'97 codec support in OSS/Free sucks. Both the Dell machines I've used come with this braindead sound hardware. The older Dell wouldn't do bitrates other than 44kHz/16-bit under OSS (or it tried to do them, with abyssmal results). ALSA fixed these issues for me. -- Charles R. Anderson <cra(a)wpi.edu> / http://angus.ind.wpi.edu/~cra/ PGP Key ID: 49BB5886 Fingerprint: EBA3 A106 7C93 FA07 8E15 3AC2 C367 A0F9 49BB 5886

First, make sure you have the proper stuff in /etc/modules.conf: # ALSA native device support alias char-major-116 snd options snd snd_major=116 snd_cards_limit=1 alias snd-card-0 snd-intel8x0 # this depends on your sound card # ALSA OSS/Free emulation support alias char-major-14 soundcore alias sound-slot-0 snd-card-0 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss Then, the correct modules are usually loaded by /etc/init.d/alsasound.
