.gitignore issues

.gitignore issues

[David Zafman]

After updating to latest master I have the following files listed by git status:

$ git status
# On branch master
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#       src/bench_log
#       src/ceph-filestore-dump
#       src/ceph.conf
#       src/dupstore
#       src/keyring
#       src/kvstorebench
#       src/multi_stress_watch
#       src/omapbench
#       src/psim
#       src/radosacl
#       src/scratchtool
#       src/scratchtoolpp
#       src/smalliobench
#       src/smalliobenchdumb
#       src/smalliobenchfs
#       src/smalliobenchrbd
#       src/streamtest
#       src/testcrypto
#       src/testkeys
#       src/testrados
#       src/testrados_delete_pools_parallel
#       src/testrados_list_parallel
#       src/testrados_open_pools_parallel
#       src/testrados_watch_notify
#       src/testsignal_handlers
#       src/testtimers
#       src/tpbench
#       src/xattr_bench
nothing added to commit but untracked files present (use "git add" to track)

These are mostly renamed binaries. If you run 'make clean' on the 
version before the name changes 
(133295ed001a950e3296f4e88a916ab2405be0cc) they'll be removed.
If you're sure you have nothing you want to save that's not
in a commit, you can always 'git clean -fdx'.

src/ceph.conf and src/keyring are generated by vstart.sh, and
I forgot to add them to .gitignore again earlier. There was
also a typo in ceph-filestore-dump - it was not renamed.
These are fixed now.

After creating more than one filesystem, how do i mount the filesystem i want?

[Isaac Otsiabah]

Josh, i created a new Ceph Filesystem with the following commands:

[root@host1]# ceph osd pool create data02 256
[root@host1]# ceph osd pool create metadata02 256

[root@host1]# ceph osd dump 2>&1 |egrep '^pool'
pool 0 'data' rep size 2 min_size 1 crush_ruleset 0 object_hash rjenkins 
pg_num 704 pgp_num 704 last_change 1 owner 0 crash_replay_interval 45
pool 1 'metadata' rep size 2 min_size 1 crush_ruleset 1 object_hash rjenkins pg_num 704 pgp_num 704 last_change 1 owner 0
pool 2 'rbd' rep size 2 min_size 1 crush_ruleset 2 object_hash rjenkins pg_num 704 pgp_num 704 last_change 1 owner 0
pool 3 'data02' rep size 2 min_size 1 crush_ruleset 0 object_hash rjenkins pg_num 256 pgp_num 256 last_change 15 owner 0
pool 4 'metadata02' rep size 2 min_size 1 crush_ruleset 0 object_hash rjenkins pg_num 256 pgp_num 256 last_change 17 owner 0


[root@host1]# ceph mds newfs 4 3 --yes-i-really-mean-it
[root@host1]# mount -t ceph 10.10.0.190:6789:/  /mnt/ceph


After i mounted as shown above and copied files to the mount point, the data 
went to the new  "data02" pool of the new filesystem rather than the old default "data" pool. My question is, if i have more than one 
filesystem, how do i mount  the  filesystem i want to be able to read 
from and write to the correct pool?

Re: After creating more than one filesystem, how do i mount the filesystem i want?

[Jean-Charles LOPEZ]

Hi Isaac,

there can only be a single MDS map at a given time. So only one File System will be exposed by the Ceph Cluster.

Everytime you will run the "ceph mds newfs" command, you will just overwrite the current config. If you happen to do so, make sure you stop the MDS to cleanly generate a new MDS map with the new pools.

You need to create subdirectories on this file system and perform an in-depth mount using different sub-direcrtories if you want to split the data across the File System but always on the pools you chose when you issued the "ceph mds newfs" command

e.g.
	• MDS FS is the root /
	• Create /Dir1
	• Create /Dir2

Use an admin client to:
	• mount -t ceph host:6789:/ /mnt/ceph
	• mkdir /mnt/ceph/Dir1 then make necessary chown or chgrp for specific access through client1
	• mkdir /mnt/ceph/Dir2 then make necessary chown or chgrp for specific access through client2
To perform the in-depth mount
	• On client1 mount -t ceph host:6789:/Dir1 /mnt/ceph
	• On client2 mount -t ceph host:6789:/Dir2 /mnt/ceph

But all data will live on the same data pool and all the metadata will live in the same metadata pool.

You can of course tune each sub-directory permissions to accommodate the level of separation you need between your clients.
