Hi,
Is it possible with Lustre to configure MDS/MDT/OST on the same node ?
I would appreciate an example of creating OST on MDS please.
I am trying to create OST by following the manual but I get into
following problem.
[EMAIL PROTECTED] ~]# mkfs.lustre --fsname datafs --ost0 --
[EMAIL PROTECTED] /dev/sdb
mkfs.lustre: unrecognized option `--ost0'
mkfs.lustre v1.6.0.1
usage: mkfs.lustre <target types> [options] <device>
<device>:block device or file (e.g /dev/sda or /tmp/ost1)
target types:
--ost: object storage, mutually exclusive with mdt,mgs
--mdt: metadata storage, mutually exclusive with ost
--mgs: configuration management service - one per site
options (in order of popularity):
--mgsnode=<nid>[,<...>] : NID(s) of a remote mgs node
required for all targets other than the mgs
node
--fsname=<filesystem_name> : default is 'lustre'
--failnode=<nid>[,<...>] : NID(s) of a failover partner
--param <key>=<value> : set a permanent parameter
e.g. --param sys.timeout=40
--param lov.stripesize=2M
--index=#N : target index (i.e. ost index within the
lov)
--comment=<user comment>: arbitrary user string (824
bytes)
--mountfsoptions=<opts> : permanent mount options
--backfstype=<fstype> : backing fs type (ext3, ldiskfs)
--device-size=#N(KB) : device size for loop devices
--mkfsoptions=<opts> : format options
--reformat: overwrite an existing disk
--stripe-count-hint=#N : used for optimizing MDT
inode size
--dryrun: just report what we would do; don't write
to disk
--verbose : e.g. show mkfs progress
--quiet
mkfs.lustre: exiting with 1 (Operation not permitted)
Thanks for help
