[smb] Samba cannot connect: NT_STATUS_UNSUCCESSFUL

[archlinuxarm2]

After smbd upgrade (I think) I get the following service errors upon connecting from a Windows machine (Raspberry PI2):

$this->bbcode_second_pass_code('', 'Feb 27 20:32:36 alarmpi smbd[4067]: file_new failed: NT_STATUS_UNSUCCESSFUL

This is probably the relevant error: tdb_expand overflow detected current map_size[4294967295] size[264]!.

I have no clue what's causing it. Googled all errors but couldn't find anything related.

Any ideas?

Found it: /var/cache/samba/smbXsrv_open_global.tdb is over 4GIG, which is giving the overflow. Removed the file, but now I'm getting:

tdb(/var/cache/samba/smbXsrv_open_global.tdb): expand_file write of 8192 bytes failed (No space left on device)

While I have enough space left in /var/cache/samba. Any ideas?

Edit: fixed it finally. /dev/root was full so I removed some old packages from pacman from /var/cache/pacman. Everything solved now!
