[mythtv-users] Directory not writeable

[Stephen Worthington]

I have recently created a new storagegroup, using a new directory on
each of my recording partitions.

mysql> select * from storagegroup order by groupname,dirname;
+----+---------------------------+----------+-------------------------------+

Today I discovered that mythbackend.log is showing errors for each of
the new directories:

storagegroup.cpp:763 (CheckAllStorageGroupDirs) SG(Default_crw-pvr):
Group 'Default_crw-pvr' wants to use directory
'/mnt/rec1/crw-pvr_recordings/', but this directory is not writeable.

Recordings that are scheduled to record to the new storagegroup are in
fact recording to the Default storagegroup.  But the new directories
are all world writeable, exactly like my Default directories:

root at mypvr:/var/log/mythtv# ll /mnt/rec1
total 1064
drwxrwxrwx  5 root root     40 Oct 12 02:40 ./
drwxrwxrwx 31 root root   4096 Oct  8 16:24 ../
drwxrwxrwx  2 root root   4096 Oct 31 19:34 crw-pvr_recordings/
drwxrwxrwx  4 root root     32 Aug 23  2014 images/
drwxrwxrwx  2 root root 200704 Nov  3 16:20 recordings/

If I login as my frontend user (mythtv group) and create a file in the
/mnt/rec1/crw-pvr_recordings/ directory, it works.

Does anyone have any ideas as to what the problem might be?
