[Lustre-discuss] lustre and rssh

[Eudes PHILIPPE]

I’ll try another system
 very very strange
 using chroot system on openssh

http://www.debian-administration.org/articles/590

 

chown root.root /home/user

mkdir /home/user/backup

chown user:sftponly /home/user/backup

 

when I’ve not lustre mounted, it’ work fine:

sftp  user at 127.0.0.1

pwd

Remote working directory: /backup

sftp> mkdir test

sftp> ls

test

 

now..

mount -t lustre -o flock,auto 192.168.45.20 at tcp0:/mdsT /home

df -h

192.168.45.20 at tcp0:/mdsT   3,0G  102M  2,8G   4% /home

 

sftp  user at 127.0.0.1

pwd

Remote working directory: /backup

sftp> ls

Couldn't get handle: Failure

sftp> mkdir test

Couldn't create directory: Failure

Exit

 

Retry again :

sftp  user at 127.0.0.1

sftp> pwd

Remote working directory: /

sftp> ls

Couldn't get handle: Failure

sftp> cd /backup

Couldn't canonicalise: Failure

 

 

 

Have an idea?

Hi,

 

I’ve a strange problem with rssh on my client. It’s 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 it’s the same problem.

 

Someone have an idea howto chroot sftp environnement on lustre?

 

Regards
