Re: [zfs-discuss] ZFS with SAN's and HA

[Peter Karlsson]

Hi Michael,

Have a look at this Blog/WP 
http://blogs.sun.com/TF/entry/new_white_paper_practicing_solaris for an 
example on how to use a iSCSI target from a NAS device as storage, you 
can just replace the tomcat/mysql HA services with HA nfs and you have 
what you are looking for.

Lao,

I had a look at the HAStoragePlus etc and from what i understand that's to 
mirror local storage across 2 nodes for services to be able to access 'DRBD 
style'.

Having a read thru the documentation on the oracle site the cluster software 
from what i gather is how to cluster services together (oracle/apache etc) and 
again any documentation i've found on storage is how to duplicate local storage 
to multiple hosts for HA failover. Can't really see anything on clustering 
services to use shared storage/zfs pools.

Peter,

what would you expect for root?
That is the user I am at.


root is default mapped to annon, if you don't specifically export it 
with the option to allow root on one or more clients to be mapped to 
local root on the server.


zfs set sharenfs=rw,root=host zpool/fs/to/export

where host is a ':' separated list of hosts.

Alternatively, if you want root from any host to be mapped to root on 
the server (bad idea), you can do something like this


zfs set sharenfs=rw,anon=0 zpool/fs/to/export

to allow root access to all hosts.

/peter


Like I already stated it is NOT a UID or GUID issue.
Both systems are the same.


Try as a different user that have the same uid on both systems and have 
write access to the directory in qustion.

Hi Phillip,

What's the permissions on the directory where you try to write to, and
what user are you using on the client system, it's most likely a UID
mapping issue between the client and the server.

I can mount the filesytem just fine but I am unable to write to it.
showmount -e shows my mount is set for everyone.
the dfstab file has option rw set.

So what gives?

Re: [zfs-discuss] Mirroring USB Drive with Laptop for Backup purposes

[Peter Karlsson]

Hi Matt,

Don't know if it's recommended or not, but I've been doing it for close 
to 3 years on my OpenSolaris laptop, it saved me a few times like last 
week when my internal drive died :)

Hi,

Just wondering whether mirroring a USB drive with main laptop disk for
backup purposes is recommended or not.

Current setup, single root pool set up on 200GB internal laptop drive :

$ zpool status
pool: rpool
state: ONLINE
scrub: non requested
config :
NAME STATE READ WRITE CKSUM
rpool ONLINE 0 0 0
c5t0d0s0 ONLINE 0 0 0


I have a 320GB external USB drive which I'd like to configure as a
mirror of this root pool (I know it will only use 200GB of the eternal
one, not worried about that).

Plan would be to connect the USB drive, once or twice a week, let it
resilver, and then disconnect again. Connecting USB drive 24/7 would
AFAIK have performance issues for the Laptop.

This would have the added benefit of the USB drive being bootable.

- Recommended or not ?
- Are there known issues with this type of setup ?


cheers

I thought I had heard forever ago that the native cifs implementation 
wouldn't ever be put back to solaris10 due to the fact it makes 
significant changes to the kernel.  Maybe I'm crazy though.

Re: [zfs-discuss] Solaris10 10/09 ZFS shared via CIFS?

Hi Trevor,

The native CIFS/SMB stuff was never backported to S10, so you would have 
to use the Samba on your S10 vm

Re: [zfs-discuss] ZFS flar image.

Hi Greg,

We did a hack on those lines when we installed 100 Ultra 27s that was 
used during J1, but we automated the process by using AI to install a 
bootstrap image that had a SMF service that pulled over the zfs 
sendfile, create a new BE and received the sendfile to the new BE. Work 
fairly OK, there where a few things that we to run a few scripts to fix, 
but at large it was smooth I really need to get that blog entry done :)

The only downfall to my method is that I still have to run the full 
OpenSolaris installer, and I can't exclude anything in the archive.


Essentially, it's a poor man's flash archive.

Hi Tobias,

I did this for a large lab we had last month, I have it setup  
something like this.

zfs snapshot  [EMAIL PROTECTED]
zfs send -i [EMAIL PROTECTED] [EMAIL PROTECTED] | ssh server2 zfs recv  rep_pool
ssh zfs destroy [EMAIL PROTECTED]
ssh zfs rename [EMAIL PROTECTED] [EMAIL PROTECTED]
zfs destroy [EMAIL PROTECTED]
zfs rename [EMAIL PROTECTED] [EMAIL PROTECTED]

I was using this for a set up with on master systems and 100 system  
that I replicated the zpool to, and I had scripts that was used when a  
student logged out to do a zfs rollback [EMAIL PROTECTED] to reset it to  
known state to be ready for a new student. I don't have the actual  
script I used here right now, so I might have missed some flags, but  
you see that basic flow of it.

Re: [zfs-discuss] Image with DD from ZFS partition

[Peter Karlsson]

Hi Hans,

Think what you are looking for would be a combination of a snapshot  
and zfs send/receive, that would give you an archive that you can use  
to recreate your zfs filesystems on your zpool at will at  later time.  
So you can do something like this

Create archive :
zfs snapshot -r [EMAIL PROTECTED]
zfs send -R [EMAIL PROTECTED] > mypool_archive.zfs

Restore from archive:
zpool create mynewpool disk1 disk2
zfs receive -d -F < mypool_archive.zfs


Doing this will create an archive that contains all descendent file  
systems of mypool, that can be restored at a later time, with out  
depending on how the zpool is organized.

As myself:

So I create a zpool on Solaris

bash-3.2$ ls -ld /ztst

So that works, so something is strange with the zpool I created in OSX

That's the default on OSX, as I created the file system on OSX

On Solaris it reports delegation on
bash-3.2$ /sbin/zpool get all zpace

[zfs-discuss] zpool shared between OSX and Solaris on a MacBook Pro

[Peter Karlsson]

Hi,

I got my MacBook pro set up to dual boot between Solaris and OSX and I  
have created a zpool to use as a shred storage for documents etc..  
However got this strange thing when trying to access the zpool from  
Solaris, only root can see it?? I created the zpool on OSX as they are  
using an old version of the on disk format, if I create a zpool on  
Solaris all users can see it, strange

Any ideas on what might be the issue here??

Cheers,
Peter

Re: [zfs-discuss] Re: External drive enclosures + Sun Server for massstorage

[Peter Karlsson]

Hi Frank,

try man devfsadm, it will update devfs with your new disk drives. disks 
is an older command that does about the same thing.


Cheers,
Peter

Also, adding a drive that wasn't present at boot requires a reboot.


This couldn't possibly be true, unless we've taken major steps backwards
as this has always been possible (at least on sparc)


It is true.  Try it.
