Hello,
I wanted to ask some clarifiaction on ldev.conf usage and features.
I am using ldev.conf only on my ZFS lustre OSSes and MDS.
Anyway I hae a doubt on what should go in that file.
I have seen people having only the metadata configuration in it like for
example:
mds01 - mgs zfs:lustre01-mgs/mgs
mds01 - mdt0 zfs:lustre01-mdt0/mdt0
and people filling hte file with both mgs settings and listing also all
the OSSes/OSTs then spreading the same ldev.conf file over all the OSSes
like in this example with
3 OSSes where each one has one OST:
mds01 - mgs zfs:lustre01-mgs/mgs
mds01 - mdt0 zfs:lustre01-mdt0/mdt0
#
drp-tst-ffb01 - OST01 zfs:lustre01-ost01/ost01
drp-tst-ffb02 - OST02 zfs:lustre01-ost02/ost02
drp-tst-ffb03 - OST03 zfs:lustre01-ost03/ost03
is this correct or only the metadata information should stay in ldev.conf ?
Also can ldev.conf be used with ldiskfs based cluster ? On ldiskfs based
clsuters I usually mount the metadata partition and OSS partitions in
fstab and my ldev.conf is empty.
thanks
Rick
