I'm using a mostly clean Ubuntu 14.04 install.
I can mount the device successfully, using
sudo mount -t ext4 /dev/sda4 /mnt/share. However, when I run
sudo mount -a, I get the error
mount: wrong fs type, bad option, bad superblock on /dev/sda4, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so
Then, when I run
dmesg tail I see:
EXT4-fs (sda4): Unrecognized mount option "fmask=0111" or missing value
fmask should be a valid value. Here is the relevant line from
UUID=45099f0b-8d10-4fd7-8214-b0a070dc0be7 /mnt/share ext4 errors=remount-ro,fmask=0111,dmask=0000 0 2
It may help to know that I believe this was working before I restarted the computer after installing some updates. (However, this is the first time I've restarted the computer since getting the mount up and running). Can anyone tell me what the problem here is?
