Strange again..... i'll try with ftp...
When I want to upload a file, I've:
553 Can't open that file: Identifier removed (and again, if /home is not a
lustre partition, it's good...)
I prefer ssh than ftp (here ftp with tls), but I've the same problem :(

.... i don't know what is the mistake, but... finaly it's the same problem
in 32 bits, impossible to chroot correctly on client, except if /home is not
lustre partition...
Very very strange
I can connect, but.. ls:
Couldn't get handle: Failure
nobody has any idea? I'm completely stuck on the project I have to realize

Ouah !
I compil new kernel and lustre for client, in 32 bits
And sftp chroot works
fine
Have an idea why its a problem in 64 bits? I think it would be better to
have the client in 64-bit?

Hi,
Ive a strange problem with rssh on my client. Its impossible to make a
chroot environnement on the mounted mds.
Mds is mounted on /home.
If I umount /home, and make my chroot environnement, it work fine (copy
librairies on /home/system, and cp Rl /home/system to /home/users/user1)
When I mount /home (lustre), connection always close.. (copy librairies on
/home/system, and cp Rl /home/system to /home/users/user1)
sftp -v user1 at 127.0.0.1
.
.
.
debug1: client_input_channel_req: channel 0 rtype exit-status reply 0
debug1: client_input_channel_req: channel 0 rtype eow at openssh.com reply 0
debug1: channel 0: free: client-session, nchannels 1
debug1: fd 0 clearing O_NONBLOCK
Transferred: sent 1424, received 1960 bytes, in 0.1 seconds Bytes per
second: sent 16860.4, received 23206.8
debug1: Exit status 1
Connection closed
I see on google I must mount with option flock, but its the same problem.
Someone have an idea howto chroot sftp environnement on lustre?
Regards
