/etc/fstab skip on error

I created a partition called /dev/sdb1 in my Ubuntu VM. But I didn’t create a filesystem for this partition and so of course it will not get mounted.

Then put following entry in fstab.

/dev/sdb1   /mnt/       auto    defaults,nobootwait     0   2

And rebooted VM. Server got rebooted with following error msg in syslog

suku@ubuntu-vm:~$ grep sdb1 /var/log/syslog

What is nobootwait:

nobootwait can be applied to non-remote filesystems to explicitly instruct mountall(8) not to hold up the boot for them.

Maybe it will be better to write a script to mount something after boot? For example, put string with noauto to fstab and mount it via rc.local

For some flavors nobootwait and for for example xfs file systems no work
