[Lustre-discuss] Lustre FS - OST external journal and lustre_createcsv

[Mail System]

Hello

I use external journal for OST, but at creation of a configuration file 
(/usr/sbin/lustre_createcsv) there is an error

lustre_createcsv: ERROR: lustre_createcsv: get_journalsize () error: 
remote command error: debugfs 1.41.6.sun1 (30-May-2009)

I have checked up the given script /usr/sbin/lustre_createcsv and have 
found a place where there is an error

In the given fragment of a code on OST server the command which should 
be executed should deduce value Journal inode:

debugfs-R ' stats-h ' $ {target_devname} | grep ' Journal inode:'

$ {target_devname}  == my OST device (/dev/sdb)

I have executed the given command on OST server but parametre Journal 
inode: in a command conclusion there was no because I used external 
journal
