Veritas Flexible Storage Sharing
Veritas Flexible Storage Sharing (FSS) is a new SFHA 6.1 feature that lets you
configure a 'shared-nothing' storage volume. It is based upon Cluster Filesystem
(CFS) but unlike base CFS it doesn't require shared storage (SAN, iSCSI, etc..).
You can read more about FSS here:
http://www.symantec.com/connect/blogs/configure-flexible-storage-sharing-using-veritas-operations-manager-61
Unlike the blog post above that uses the VOM GUI, I will be configuring FSS
between two virtual machines in an old-fashioned style (CLI). I decided to write
this blog because I couldn't find enough information in one place on how to
setup FSS using the non-GUI stuff.

Lab setup and specs for each VM:
vcs14: RHEL6.6.z, 8Gb RAM, 32*8Tb local disks, 16*2Tb shared disks (these won't
be used).
vcs15: RHEL6.6.z, 8Gb RAM, 32*8Tb local disks, 16*2Tb shared disks (these won't
be used).
I won't go over the details of setting up a CFS cluster. Here are some of the
things you would normally see after CFS has been setup (Think cfscluster config
and cfscluster start):
[root@vcs14 ~]# gabconfig -a

There are 32^H^H^H33 8Tb disks per system, like I said. :)
-
Meaningful disk names (Optional).
I don't like the default disk names, so let's change them to something
meaningful (remember to vxdisksetup the disks if you haven't already):
[root@vcs14 ~]# lsblk -d|grep '^sd.*8T'|awk '{ print $1 }' > /tmp/disks
[root@vcs14 ~]# seq -w 0 32 > /tmp/nums
[root@vcs14 ~]# paste /tmp/disks /tmp/nums |awk '{ print "vxdmpadm setattr dmpnode",$1,"name=ssd_" $2 }' > /tmp/names.sh
[root@vcs14 ~]# bash /tmp/names.sh
[root@vcs14 ~]# vxdisk list

Let's do the same for vcs15 ( you get the picture..) :

[root@vcs15 ~]# seq -w 0 32 > /tmp/nums

Now export the disks to the remote cluster nodes:
[root@vcs14 ~]# vxdisk list|grep ^ssd|awk '{ print $1}' |xargs -n1 vxdisk export
[root@vcs15 ~]# vxdisk list|grep ^ssd|awk '{ print $1}' |xargs -n1 vxdisk export
Look at the vxdisk output, now each node sees the disks that were exported on
its sibling:
On vcs14, we see the disks from vcs15

Configure an FSS diskgroup (do this on only one node):
[root@vcs14 ~]# vxdisk list|egrep 'ssd'|awk '{ print $1}' > /tmp/alldisks
* Create the diskgroup on one node (notice how it shows up on both nodes):
[root@vcs14 ~]# vxdg -o fss -s init FSS00dg $(cat /tmp/alldisks )
[root@vcs14 ~]# vxdg list
NAME STATE ID
FSS00dg enabled,shared,cds 1423072143.104.vcs14
[root@vcs15 ~]# vxdg list

Create a volume in the FSS diskgroup to hold our data:
[root@vcs14 ~]# vxdctl -c mode

[root@vcs14 ~]# vxassist -g FSS00dg maxsize nmirror=2 layout=mirror-stripe stripeunit=512k
Maximum volume size: 566933245952 (276822874Mb)
* To be on the safe side: 256tb = 262144g, pick 262144g - 2g : 262142g
(See the footnotes for more information on this)
[root@vcs14 ~]# vxassist -g FSS00dg make fss0_lv 262142g nmirror=2 layout=mirror-stripe stripeunit=512k

Now, create a filesystem on that volume so we can make use of it (Do this on
only one node):
[root@vcs14 ~]# mkfs -t vxfs /dev/vx/dsk/FSS00dg/fss0_lv
version 10 layout
549755813888 sectors, 34359738368 blocks of size 8192, log size 32768 blocks
rcq size 8192 blocks
largefiles supported
maxlink supported
CFSmount the Filesystem (Do this on only one node):
[root@vcs14 ~]# cfsmntadm add FSS00dg fss0_lv /shared/fss0 fss00_SG all=crw
Mount Point is being added...
/shared/fss0 added to the cluster-configuration

Configure a Service Group (Optional)
Add a service group to make it show in the Cluster configuration and autostart
the right things (tm):
[root@vcs14 ~]# haconf -makerw
[root@vcs14 ~]# hares -modify vxfsckd ActivationMode cvmdg sw FSS00dg sw -sys vcs14
[root@vcs14 ~]# hares -modify vxfsckd ActivationMode cvmdg sw FSS00dg sw -sys vcs15
[root@vcs14 ~]# hagrp -add fss00_SG
[root@vcs14 ~]# hagrp -modify fss00_SG SystemList vcs14 0 vcs15 1
[root@vcs14 ~]# hagrp -modify fss00_SG Parallel 1
[root@vcs14 ~]# hagrp -modify fss00_SG AutoStartList vcs14 vcs15
[root@vcs14 ~]# hagrp -modify fss00_SG SourceFile "./main.cf"
[root@vcs14 ~]# hares -add cfsmount_res CFSMount fss00_SG
[root@vcs14 ~]# hares -modify cfsmount_res BlockDevice "/dev/vx/dsk/FSS00dg/fss0_lv"
[root@vcs14 ~]# hares -modify cfsmount_res MountPoint "/shared/fss0"
[root@vcs14 ~]# hares -add cvmvoldg_res CVMVolDg fss00_SG
[root@vcs14 ~]# hares -modify cvmvoldg_res CVMVolume fss0_lv
[root@vcs14 ~]# hares -modify cvmvoldg_res CVMDiskGroup FSS00dg
[root@vcs14 ~]# haconf -makerw
This should result in this output:

Let's do some writes from both nodes (remember that these are Virtual Machines
with emulated disks so the performance would be better if I had real physical
DAS storage):

256Tb (the max size of a VxFS filesystem) is 262144gb. When I attempted to
create a Filesystem on my 256Tb volume, I was greeted with this error:
[root@vcs14 ~]# mkfs -t vxfs /dev/vx/dsk/FSS00dg/fss00_lv
UX:vxfs mkfs.vxfs: ERROR: V-3-26258: File system size cannot exceed 262144 GB
Also, I noticed that sometimes vxvol wouldn't start a 256Tb volume so I dropped
the ball and went for 262142gb for both the volume and filesystem.

SFCFSHA software versions:
[root@vcs14 ~]# rpm -q VRTSvxfs VRTSvxvmVRTSvxfs-6.1.1.202-RHEL6.x86_64VRTSvxvm-6.1.1.100-RHEL6.x86_64
If you are on SF6.1+latest patches (As of Jan 2015) and you have a CFS
filesystem that's over 100Tb in size, contact Veritas and ask for the following
patch: fs-rhel6_x86_64-HotFix-6.1.1.007.tar.gz or
fs-rhel6_x86_64-HotFix-6.1.1.202.tar.gz.
The tracking number for this issue is e3233276.
Without the patch, when unmounting the filesystem, you might get a cpu soft
lockup. Nothing happens but it slows down the whole unmounting procedure. Here's
the sign you're running into this issue:
[root@server101 CFSMount]# umount /vx/vol01Message from syslogd@server101 at Oct 23 21:36:03 ...kernel:BUG: soft lockup - CPU#0 stuck for 67s! [vx_ctl_thread:19524]
