Re: [indiana-discuss] [sysadmin-discuss] /dev/null disappeared and unable to recreate it
Hi François, some suggestions: * Recreate /dev mkdir /dev.new cd /dev ; find . | cpio -ldump /dev.new mv dev dev.old mv dev.new dev devfsadm * Have you checked that your system isn't compromised?

cd /dev ; find . | cpio -ldump /dev.new Sorry, ldump did only work when /dev was not a seperate fs, use dump instead: cd /dev ; find . | cpio -dump /dev.new ___ indiana-discuss mailing list indiana-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/indiana-discuss
Re: [indiana-discuss] [sysadmin-discuss] /dev/null disappeared and unable to recreate it
Francois, I'm reposting this on indiana-discuss to see if anyone on that list can provide some input. Is this happening during a netinstall? Can you provide the output of ls -l /dev/null?

Re: [indiana-discuss] [sysadmin-discuss] /dev/null disappeared and unable to recreate it
Hi, Looks like the devname filesystem is confused. DO the following 1. Use ln -s to create /dev/null manually # ln -s ../devices/pseudo/[EMAIL PROTECTED]:null/dev/null 2. Do a reboot -d to generate a kernel core file 3. File a bug and attach core file to bug report. The system should come up normally after a reboot. BTW, mention the exact conditions when this problem happened (was it normal boot or install boot - did you do anything in /dev etc.) Vikram - Original Message From: [EMAIL PROTECTED] [EMAIL PROTECTED] To: François Feugeas [EMAIL PROTECTED] Cc: [EMAIL PROTECTED]; indiana-discuss@opensolaris.org Sent: Thursday, August 21, 2008 1:10:48 PM Subject: Re: [indiana-discuss] [sysadmin-discuss] /dev/null disappeared and unable to recreate it Francois, I'm reposting this on indiana-discuss to see if anyone on that list can provide some input.

Re: [indiana-discuss] [sysadmin-discuss] /dev/null disappeared and unable to recreate it
Hi, ok in that case you will have to take the risk of rebooting without creating /dev/null. Do a reboot -d to create a core dump file and reboot. If you have problems on reboot due to missing /dev/null, boot the Live CD, mount the hard disk and create /dev/null via ln. That should succeed as you are then operating outside devname filesystem Vikram - Original Message From: François Feugeas [EMAIL PROTECTED] To: Vikram Hegde [EMAIL PROTECTED] Cc: [EMAIL PROTECTED]; [EMAIL PROTECTED]; indiana-discuss@opensolaris.org Sent: Thursday, August 21, 2008 2:05:20 PM Subject: Re: [indiana-discuss] [sysadmin-discuss] /dev/null disappeared and unable to recreate it Hello, I weren't clear the first time, but this issue is encountered on a system that has been running perfectly for a few weeks (and not during an install). Nothing special happened on that system, though OpenSSH (which we use on that system in replacement of SunSSH) crashed on us 10 minutes before we noticed /dev/null went missing. Maybe one issue caused the other. Nothing was done under /dev. As stated earlier, I am not able to create *anything* named null under /dev/ : # ln -s ../devices/pseudo/[EMAIL PROTECTED]:null/dev/null ln: cannot create /dev/null: No such file or directory # touch /dev/null touch: /dev/null cannot create touch /dev/anything succeeds, though Best regards, François Feugeas - Original Message From: [EMAIL PROTECTED] [EMAIL PROTECTED] To: François Feugeas [EMAIL PROTECTED] Cc: [EMAIL PROTECTED]; indiana-discuss@opensolaris.org Sent: Thursday, August 21, 2008 1:10:48 PM Subject: Re: [indiana-discuss] [sysadmin-discuss] /dev/null disappeared and unable to recreate it Francois, I'm reposting this on indiana-discuss to see if anyone on that list can provide some input.
