Hey gang,
I'm hoping that someone can help me out. I've been beating my head
against this for a few days now and can't seem to come up with a reason as
to why this is happening.
We've got two 240s running VxFS/VxVM/HA and acting as a
primary/secondary NFS server, with an A5200 as the storage unit.
I've got about 20 some odd systems ranging from V100's to V210s that
will be mounting the NFS "cluster" (I use that term loosely here) as
application and web services systems in r/o mode and I thought that this
would be the perfect situation for cacheFS. First because I can foresee the
need in the future to scale, and I might as well get it setup now and
secondly because I like the added piece of mind that the cachefs disconnect
(if used with cachefspack) feature gives me.
My problem is that I can't get cacheFS to work properly on system
reboots, even though the proper entries are in /etc/vfstab.
Vfstab reads as follows (all on one line obviously):
nfs-web:/export/home - /home cachefs 7 yes
nosuid,backfstype=nfs,cachedir=/usr/cache,local-access
What happens is that the system comes up and the share gets mounted,
but the cache-mount point changes every time there's a reboot:
jeffm@web-1(pts/1):~> df -h /portal
Filesystem size used avail capacity Mounted on
/usr/cache/.cfs_mnt_points/nfs-web:_export_prod_web_portal_3
339G 101M 318G 1% /portal
That /usr/cache/.cfs_mnt_points/nfs-web:/_export_prod_web_portal_3
line will change to foo_bar_portal_4 the next time the system boots.
Now I've run cachefs in the past, albeit on older versions of
Solaris (2.5, 2.6) and never noticed this problem before. But because I
didn't notice it, doesn't mean that it wasn't happening. So maybe it's
normal(?)
Another fun thing I've noticed is that cachefsd is not being
started. One of the reasons for me to move to cacheFS is that I like the
disconnect feature that cachefs provides. However, for that to work I need
cachefsd.
If I unmount / remount the share, via "umount /portal ; mount
/portal" cachefsd starts right up _AND_ my cache mount point stays the same.
That number at the tail end doesn't increment.
According to docs.sun.com, cachefsd is supposed to be started
automatically from inetd when a mount_cachefs is invoked... isn't that what
the system does when it's mounting vfstab entries with the fstype of
cachefs?
I checked to make sure that rpc and the cachefs entries in
inetd.conf existed, and rpcbind is running, and everything seems to be in
working order. I also double checked to make sure that I didn't miss
re-enabling the nfs.client and cacheFS rc2.d scripts after JASS had disabled
them (they were fine).
Anyone seen this before? Solaris 9 12/03 release. Latest (as of
3/1/04) recommended patch set installed. Highly customized package set
installed (SUNWreq, plus a few minor additions - web servers don't need
SUNWall!).
