How to unmount entware temporarily?

[mobileman88]

Hi, I would like to unmount the entware USB temporarily to perform e2fsck on it, but I keep getting filesystem busy. Upon restart I am getting "EXT2-fs warning: mounting unchecked fs, running e2fsck is recommended" . I suspect this is due to a power trip that happened at home.

Nevermind. I installed "lsof" found all the processes which was keeping the partition mounted, killed them, umounted and ran e2fsck. Have a good weekend

Hi, I trie to do the same.

lsof | grep entware > files

where entware is the mount point of my stick

then I did

cat files | awk '{print "kill " $2}' > ent.sh

./ent.sh to kill all pids linking to entware files.

but still cannot umount because it says resource is busy

am I missing something?

Thanks a lot

Install and use fuser:

# fuser -mv /tmp/mnt/VERBATIM
                     USER        PID ACCESS COMMAND
/tmp/mnt/VERBATIM:   admin    kernel mount /tmp/mnt/VERBATIM
                     admin      1367 F.... smbd

                     USER        PID ACCESS COMMAND
/tmp/mnt/VERBATIM:   admin    kernel mount /tmp/mnt/VERBATIM
                     admin      1367 F.... smbd

Where to find fuser? It is not listed as a package in entware repo ...

opkg install psmisc

Thanks!

Install and use fuser:

# fuser -mv /tmp/mnt/VERBATIM
                     USER        PID ACCESS COMMAND
/tmp/mnt/VERBATIM:   admin    kernel mount /tmp/mnt/VERBATIM
                     admin      1367 F.... smbd

Thanks a lot. That perfectly worked!

Running:
>fuser -mv /tmp/mnt/entware
it reported:

/tmp/mnt/entware:
makksi kernel swap /tmp/mnt/entware/swap
makksi kernel mount /tmp/mnt/entware
makksi 1254 F..e. lighttpd
makksi 1255 ..ce. php-fcgi
makksi 1261 ...e. transmission-da
makksi 1275 ..ce. php-fcgi
makksi 1276 ..ce. php-fcgi
makksi 1953 F.... minidlna
makksi 1955 F.... minidlna
makksi 1956 F.... minidlna

Then I used -to kill all the related processes-:
>fuser -mkv /tmp/mnt/entware

Running again fuser -mv...

>fuser -mv /tmp/mnt/entware
it reported:

/tmp/mnt/entware:
makksi kernel swap /tmp/mnt/entware/swap
makksi kernel mount /tmp/mnt/entware

Then I had to do:

>swapoff /tmp/mnt/entware

Only at this point I had correctly unmount entware partition using

>umount /tmp/mnt/entware


Thanks again!
