Public bug reported:
This is from the ubuntu-phone list.
Hi,
I digged into this, esp. into why the mounted microSD was busy; there is
a process running with the name 'mediascan' and as the SD contained some
100.000 files (map tiles of OpsenStreetMap), this would run hours, I think:
phablet@ubuntu-phablet:~$ sudo lsof 2>/dev/null | fgrep /media/phablet/
mediascan 2077 phablet 13r DIR 179,97 32768 4906
/media/phablet/7895-9F4B/Maps/OSM/18/139590
gdbus 2077 2091 phablet 13r DIR 179,97 32768 4906
/media/phablet/7895-9F4B/Maps/OSM/18/139590
gmain 2077 2323 phablet 13r DIR 179,97 32768 4906
/media/phablet/7895-9F4B/Maps/OSM/18/139590
when you kill this, it comes up again, but when you fire
up the 'umount' right away after the kill, you are lucky:
phablet@ubuntu-phablet:~$ sudo lsof 2>/dev/null | fgrep /media/phablet/
mediascan 7302 phablet 9r DIR 179,97 32768 4900
/media/phablet/7895-9F4B/Maps/OSM/18/139584
gdbus 7302 7304 phablet 9r DIR 179,97 32768 4900
/media/phablet/7895-9F4B/Maps/OSM/18/139584
phablet@ubuntu-phablet:~$ sudo kill -9 7302
phablet@ubuntu-phablet:~$ sudo umount /media/phablet/7895-9F4B
phablet@ubuntu-phablet:~$ mount | fgrep vfat
phablet@ubuntu-phablet:~$
Now I could reformat the card with the SD card app:
SD Card Management --> Format (2 times, 1st error)
it gets mounted and has some initial dirs created by the
SD Card app:
phablet@ubuntu-phablet:~$ mount | fgrep vfat
/dev/mmcblk1 on /media/phablet/882E-8C17 type vfat
(rw,nosuid,nodev,relatime,uid=32011,gid=32011,fmask=0022,dmask=0022,codepage=cp437,iocharset=iso8859-1,shortname=mixed,showexec,utf8,flush,errors=remount-ro,uhelper=udisks2)
phablet@ubuntu-phablet:~$ ls -l /media/phablet/882E-8C17
total 20
drwxr-xr-x 2 phablet phablet 4096 Apr 4 10:40 Documents
drwxr-xr-x 2 phablet phablet 4096 Apr 4 10:40 Downloads
drwxr-xr-x 2 phablet phablet 4096 Apr 4 10:40 Music
drwxr-xr-x 2 phablet phablet 4096 Apr 4 10:40 Pictures
drwxr-xr-x 2 phablet phablet 4096 Apr 4 10:40 Videos
SD Card Management --> Unmount works too:
phablet@ubuntu-phablet:~$ mount | fgrep vfat
phablet@ubuntu-phablet:~$
re-inserting the microSD now gives no errors and the card is
mounted:
$ mount | fgrep vfat
/dev/mmcblk1 on /media/phablet/882E-8C17 type vfat
(rw,nosuid,nodev,relatime,uid=32011,gid=32011,fmask=0022,dmask=0022,codepage=cp437,iocharset=iso8859-1,shortname=mixed,showexec,utf8,flush,errors=remount-ro,uhelper=udisks2)
phablet@ubuntu-phablet:~$ find /media/phablet/882E-8C17

/media/phablet/882E-8C17/Documents

/media/phablet/882E-8C17/Music
/media/phablet/882E-8C17/Pictures
/media/phablet/882E-8C17/Videos
phablet@ubuntu-phablet:~$ df -kh /media/phablet/882E-8C17
Filesystem Size Used Avail Use% Mounted on
/dev/mmcblk1 7.5G 24K 7.5G 1% /media/phablet/882E-8C17
Last question remains: What does the 'mediascan' exactly und what
will it do when I restore the 100.000 files again? Is there a way
to trimm 'mediascan' that it should ignore some dirs?
Thanks
