Title: Server Crash: switchroot: mount failed: No such file or directory
Post by: LANMonkey on May 17, 2013, 07:44:04 PM

I woke up this morning to find that my SME server had crashed.  The monitor login was unresponsive.  I did a hard reboot and here are some of the messages that I managed to write down:

Code: [Select]

Recovery required on read only file system
Write access will be enabled during recovery

ide: failed opcode was unknown
hda: drive not ready for command

...

end request I/o error dev hda sector 440693

You are experiencing a crash disk with bad sectors so the system is not able to start. As i can see yo have only one hard disk, i hope that i make a mistake but there is no mention to hdb.
You can try to start your system with a rescue-cd but in the meanwhile it is time to look about backups.
