Sometimes when I remove SD card I can notice that when I reinsert it - it doesn't mount by itself.Also I've notice that umount process is stalled and I cannot kill it (not even with -9).I use Ubuntu 14.04.Any idea what I do wrong?
umount stalled and unable to kill its process
ubuntu;mount;kill
First: get out from that directory in terminal :) Jocking.. but not so much,  thinking how many times I run umount and it gives me an error because I'm actually inside the folder. I would go in terminal and try lsof | grep ssdDirectory, to see what it tells is using that dir.Example output of lsof | grep /mnt/share, where share is mounted.COMMAND     PID  TID    USER   FD      TYPE             DEVICE  SIZE/OFF       NODE NAMElsof      11930         root  cwd       DIR              253,2        15     213678 /mnt/shareThis is telling that lsof is executing exactly from /mnt/share with FD (File Descriptor) cwd, the current working directory. If you see the same.. get out from that directory ;))
