From: Arthur Marsh on 2 Feb 2010 07:00 Hi, I found that initscripts seems to attempt to run fsck on non-existent devices that appear in /etc/fstab, and different fsck programs for different filesystem types give different error codes. What is the easiest way to set up Debian to automatically mount specific devices if they are present, but not cause a boot failure when they are absent?

"man fstab" says that if the <passno> digit is other than zero, "fsck" will try to check that mount point.

I have devices (usually flashdrives and or digital cameras) that may or may not be present during boot and they don't cause boot failure. But I guess you're talking about differnt devices ?? - -- Frank -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iQEcBAEBAgAGBQJLaEe6AAoJEMEDyLTvrVhj7uUH/1MPvgGpIlYep0pyaQIr7gAN M8yO1cLsIpjBA/43I10TFeBIVxhIbifii+JN0iDvK/FUOn0SUoopXF9fSCkQR357 HbxvCwSGInSshFGxGt5vEf9c2a9agVqlc++6BxY2FaP6JmkiqHRim0i8D8iX7bMy 6pucIOUSnS+dLsD1EKwsaqJP83X8Z99JOuHfMh1fykBGzb0S4uDSX0aAl27k4gHr T5orATLernss7V/gakPZ8haXTVhOYQJinnlI3quroipjx3Ji1yxIu1ygg4mA1hJQ 3A0gVs2TGKaDC/7mjWP3q54//OoNlUNqZapWMB0vyJYeO0FgRs4H51PJr7yc8FY= =SBkh -----END PGP SIGNATURE----- -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

I mean devices listed as static mount points in "/etc/fstab". Usually, removable media (flash drivers and SD cards) are not listed there. I.e., if your USB drive is listed there and you have something like: # <file system> <mount point> <type> <options> <dump> <pass> /dev/sdb1 /data/backup ext3 acl,user_xattr 1 2 ^ Then fsck will try to check that mount point, either is present or not (or at least that is my understanding after reading "man fstab") :-) If you want to avoid auto-checking at all for that specific mount point, you can put a "0" (zero) in the last column). You'll have to do the checking manually. P.S. I suggest you to use LABEL or ID mount points for hard disk USB devices.

The boot process simply gives an error that the device does not exist. There is no attempt to fsck the non-existant drive. I gather this is because the system attempts to mount the non-existant drive. > > If you want to avoid auto-checking at all for that specific mount > point, you can put a "0" (zero) in the last column).
