[Bug 1318585] [NEW] NFSv3 exports not fully functional with older NFS clients
Public bug reported:
Ubuntu 12.04.4 LTS
Reproducible bug in nfs exports starting from 3.2.0-58
Starting kernel version 3.2.0-58, it is impossible to checkout any subversion project on a NFSv3 mounted share on a Solaris 10 machine.
svn co svn+ssh://svn.url/project
returns the following
svn: Can't read directory 'trunk': Value too large for defined data type
Mounting the share with NFSv2 doesn't create this problem
Possibly related to the following (excerpts from changelog):
* ext4: return 32/64-bit dir name hash according to usage type
- LP: #1257010
* nfsd: vfs_llseek() with 32 or 64 bit offsets (hashes)
- LP: #1257010
Steps to reproduce:
- On Ubuntu 12.04.4 installed both kernel versions 3.2.0-57 and 3.2.0-58
- Boot with 3.2.0-57
- Start nfs-kernel-server and export share
- mount on Solaris 10 as NFSv3 (default)
- login as share-authorized user on NFS share
- create dir and checkout svn
- ok
- Reboot nfs server with kernel 3.2.0-58
- unmount and mount share on Solaris machine
- Try to svn co again, returns error "svn: Can't read directory 'trunk': Value too large for defined data type"
It looks like 32bit NFS clients cannot handle 64 bit cookies relate to
readdir and readdirplus, so this problem might not be exclusive to
Solaris (this is the machine on which we could reproduce it)
Thanks
