I haven't read all the answers, but usually it works fine (when it is a mount for userdata that fails) to just mount everything manually: mount /usr mount /var mount /opt and so on. and after enough mounts just: /etc/init.d/sshd start and you can login as usual and fix the problem

Why does zLinux die on a bad fstab entry?

2011-06-09 Thread Bauer, Bobby (NIH/CIT) [E]
I recently had a typo in fstab for a new file system I tried to add and my system would not come back up. Thanks to everybody for helping me out and getting my system back without a major recovery effort. Any reason why zLinux dies when it finds a bad entry in fstab even though the filesystem

If /etc/fstab has markers which say this is important, then it dies. That is common for Unix/Linux/POSIX. Specifically, if you have the troubled FS set to be checked (last column something other than 0), and the check fails, the system will fall back to maint mode. Filesystems which fail to

This might be influenced by those numbers at the end of the fstab entry.. The last one indicates whether fsck should be run against it. If yours is 0, then that should prevent Linux from requiring it there. I'm not sure how badly you mucked up the syntax though...As others have said - use

Thank you everyone for your confirmation and instructions. It threw off our Linux Support person when YaSt wouldn't keep the LVM option on the disk as he was doing the install. Following the suggestions we were able to configure it and it is working now. Craig Collins State of WI, DOA, DET On

For mounting network filesystems this can be true... but for a local disk (which I'm pretty sure is the case here) - you are either put into a recovery shell or it won't come up at all and you have to recover by other means. Depends on what the error in your fstab is and what fsck option you have

Implementing the driver isn't an auditable offense.. gaining access to the volume through a DEDICATE or LINK, etc is another story - but that shouldn't discourage use of the driver. I see little difference between this and the cmsfs driver... access to a z/OS or CMS disk is auditable (or
