rsync transfer failed: File name too long (36)

[Andrew M.]

Binary package hint: rsync

Trying to rsync my encrypted home folder to another ubuntu machine (with exactly the same release and package version of rsync). Most transfers succeed, but occasionally I see:

rsync: recv_generator: mkdir "/mnt/backupuuid/mnt/home/.Private/ECRYPTFS_FNEK_ENCRYPTED.FWYZkOJAsGSXo-S.cpRFq3wvU.Dtozd29e1O4rDGDN9cc6pEme5GOKs67U--/ECRYPTFS_FNEK_ENCRYPTED.FXYZkOJAsGSXo-S.cpRFq3wvU.Dtozd29e1Oj3Vo5jUgBfJ.o-NKs.75Rbf3tBnbdAGWQ29J2e5laBE-/ECRYPTFS_FNEK_ENCRYPTED.FWYZkOJAsGSXo-S.cpRFq3wvU.Dtozd29e1OnAMGEJ-0sE.Yiwc37kTNQk--/ECRYPTFS_FNEK_ENCRYPTED.FbYZkOJAsGSXo-S.cpRFq3wvU.Dtozd29e1OwVHHPKxU7rcIFxmidLe3rp8pLAFfEgvTPilQAb4uRdmqWVGPNC9iGn5.W-fCXDmqHBnVSSWE2Nuj6l6JAUSwwOjvStnWm3f2u1mp4iaKbgmNHIlyr7wCHIS.CHnK-H.E" failed: File name too long (36)

What's the filesystem you are backing up to?
It's got to be said that is a very long filename - but it doesn't seem to be greater than
any limits I can find; most seem to be 255 for the length of any name in a filesystem, and at least 1024 for the whole length.

from: ext4
to: encfs sitting on an ext4 filesystem

i've attached the encfs xml file - perhaps this is really an encfs bug?

[Andrew M. (ender-neo)]

from the destination machine:

apt-cache policy encfs
encfs:
  Installed: 1.5.2-2
  Candidate: 1.5.2-2
  Version table:
 *** 1.5.2-2 0
        500 http://mirror.anl.gov/pub/ubuntu/ lucid/universe Packages
        100 /var/lib/dpkg/status

I did a test using mkdir and a 966 char long path name on the destination machine. Everything worked fine when I issued these commands:

backup@hoshira:/mnt/backupuuid/mnt$ sudo mkdir -p "test/thisisanextremelylongpathname1/thisisanextremelylongpathname2/thisisanextremelylongpathname3/thisisanextremelylongpathname4/thisisanextremelylongpathname5/thisisanextremelylongpathname6/thisisanextremelylongpathname7/thisisanextremelylongpathname8/thisisanextremelylongpathname9/thisisanextremelylongpathname0/thisisanextremelylongpathname1/thisisanextremelylongpathname2/thisisanextremelylongpathname3/thisisanextremelylongpathname4/thisisanextremelylongpathname5/thisisanextremelylongpathname6/thisisanextremelylongpathname7/thisisanextremelylongpathname8/thisisanextremelylongpathname9/thisisanextremelylongpathname0/thisisanextremelylongpathname1/thisisanextremelylongpathname2/thisisanextremelylongpathname3/thisisanextremelylongpathname4/thisisanextremelylongpathname5/thisisanextremelylongpathname6/thisisanextremelylongpathname7/thisisanextremelylongpathname8/thisisanextremelylongpathname9/thisisanextremelylongpathname0/thisisanextremelylongpathnameN"
backup@hoshira:/mnt/backupuuid/mnt$ echo $?
0

[Andrew M. (ender-neo)]

ok, this doesn't look like rsync's fault at all

I issued the following command on the destination machine directly, and it threw up.
backup@hoshira:~$ sudo mkdir -p "/mnt/backupuuid/mnt/test/.Private/ECRYPTFS_FNEK_ENCRYPTED.FWYZkOJAsGSXo-S.cpRFq3wvU.Dtozd29e1O4rDGDN9cc6pEme5GOKs67U--/ECRYPTFS_FNEK_ENCRYPTED.FXYZkOJAsGSXo-S.cpRFq3wvU.Dtozd29e1Oj3Vo5jUgBfJ.o-NKs.75Rbf3tBnbdAGWQ29J2e5laBE-/ECRYPTFS_FNEK_ENCRYPTED.FWYZkOJAsGSXo-S.cpRFq3wvU.Dtozd29e1OnAMGEJ-0sE.Yiwc37kTNQk--/ECRYPTFS_FNEK_ENCRYPTED.FbYZkOJAsGSXo-S.cpRFq3wvU.Dtozd29e1OwVHHPKxU7rcIFxmidLe3rp8pLAFfEgvTPilQAb4uRdmqWVGPNC9iGn5.W-fCXDmqHBnVSSWE2Nuj6l6JAUSwwOjvStnWm3f2u1mp4iaKbgmNHIlyr7wCHIS.CHnK-H.E"

[Dave Gilbert (ubuntu-treblig)]

Hi Andrew,
  I've marked this as a dupe of #344878 which is problems with ecryptfs's filename lengths

Dave

[Tyler Hicks (tyhicks)]

David - I don't believe this is a dup of bug #344878. IIUC, Andrew is backing up a file, which happens to have an eCryptfs encrypted file name, to an encfs mount point on the destination machine. The destination machine, using encfs is the one reporting ENAMTOOLONG... right Andrew?

[Andrew M. (ender-neo)]

That's correct - the destination is an encfs filesystem sitting on an ext4 drive.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

This bug is still there in Ubuntu 12.04:

Sorry, I have overlookedf the hint

Anyone used “Long Path Tool” !!

[Damien barifon (shahzadi-kohkaf)]

Try to long path tool. It is very helpful.

[robertvo (navisakhti123)]

I found this problem before but i have fixed this easily. There are many tool available for long path error. I have used Long path tool and it works great. You can try it. It is easy to fix this error using this tool.

[macho (macho)]

Can someone please post a link to Long Path Tool? The only thing I find with that name is a Windows utility.

[Frank (frank1982)]

Try Long Path Tool as it can remove any problems that you might have.
