I was copying files to a directory remote with `git annex copy`. Out of 114 files, 9 of them failed with no message, just:
copy data/foo.dat (to usbdrive...) failed
copy data/bar.dat (to usbdrive...) failed
According to strace:
31338 mkdir("/media/annex/Zp/9v/SHA256-s1362999320--d650297c8cf8c2dc0575110a52d0c5cc0ff266f294a0599f85796a6b44b23492", 0777) = -1 ENOENT (No such file or directory)
31338 mkdir("/media/annex/Zp/9v", 0777) = -1 ENOENT (No such file or directory)
31338 mkdir("/media/annex/Zp", 0777) = -1 EEXIST (File exists)
31338 stat("/media/annex/Zp", 0x7f8449f170d0) = -1 ENOENT (No such file or directory)
The filesystem is FAT32 and has weird case semantics. This was mounted by udisks with its default options:
/dev/sdb1 on /media/annex type vfat (rw,nosuid,nodev,uhelper=udisks,uid=1000,gid=1000,shortname=mixed,dmask=0077,utf8=1,showexec)
I wonder if the directory remote should use hashDirLower instead of hashDirMixed?
