Hi there, ... I had a major filesystem crash just a few minutes ago. The crash was so heavy, that I first had to think about a hardware-failure. But I didn't found anything in the logfiles. The story: Yesterday I began to play around with an experimentail jail-based virtual server setup. The 'jail world' was located under /scratch/jails/zappa/. 'inetd', 'telnetd', a 'sh' were running jailed. It sees to run rather well. Today I changed my working directory (running a regular, non-jailed shell) to /scratch and found the directory empty. 'What the hell is going on here?' I thought ran a 'ps' just to find the jailed processes running happily. I did a telnet to the virtual server, was able to login successfully and found a apparently intact filesystem. ... and then.. ... and then ... the screen froze and a few seconds later the machines rebooted silently. No tracks in the logs. Sorry, I was running X and currently have no serial console available. Therefor I just can't tell, if it was really a silent reboot or a 'not-seen' panic. The filesystem was totally hosed. 'fsck' spat out masses of 'unknown file type', 'partially allocated inode', 'incorrect block count' (with rather large discrepancies) and 'excessive bad blks' messages. Partially transcripts of 'fsck -y '-logs are available on request. System: K7/700, 256MB, sym0, fxp0 Disk: <IBM DNES-309170W SA30>> The disk contained a ca. 9GB filesystem (default newfs) mounted without any special options (on /scratch).
