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:~$ 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:~$ 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)
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?
From ubuntu-phone:
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/ phablet/ 7895-9F4B/ Maps/OSM/ 18/139590 phablet/ 7895-9F4B/ Maps/OSM/ 18/139590 phablet/ 7895-9F4B/ Maps/OSM/ 18/139590
mediascan 2077 phablet 13r DIR 179,97 32768 4906 /media/
gdbus 2077 2091 phablet 13r DIR 179,97 32768 4906 /media/
gmain 2077 2323 phablet 13r DIR 179,97 32768 4906 /media/
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/ phablet/ 7895-9F4B/ Maps/OSM/ 18/139584 phablet/ 7895-9F4B/ Maps/OSM/ 18/139584 ubuntu- phablet: ~$ sudo kill -9 7302 ubuntu- phablet: ~$ sudo umount /media/ phablet/ 7895-9F4B

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 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)
/dev/mmcblk1 on /media/
phablet@ ubuntu- phablet: ~$ ls -l /media/ phablet/ 882E-8C17

SD Card Management --> Unmount works too:

re-inserting the microSD now gives no errors and the card is
mounted:

will it do when I restore the 100.000 files again? Is there a way
