If you accidentally upgraded your root zfs pool (which is not recommended until it is supposed to be done from Oracle) do not forget to update your boot signature,  your boot archive and your grub installation -

but do not reboot before having done this, otherwise the system won't boot any more.

Don't upgrade the root pool! You won't be able to repair your system when booting from the actual Solaris 10 boot CD (09/10) as the root pool cannot be mounted then. The following steps are to make sure that your system will at least boot when you did the upgrade accidentally.


Since Kernel patch/update 144501-19, Oracle now puts zpool version 29 and zfs version 5 into production.

One visible change is the more detailed status when doing a scrub or a resilver operation:

# zpool status
  pool: rpool

In case you're interested in Sun/Oracle Openstorage, Fiberchannel Enterprise technologies or just want to drink a glass of fine beer - drop a note.

May 19th I am at Frankfurt Int'l Airport (Sheraton Airport Hotel) and from May 20th to 30th I will be staying in Cameroon meeting friends.

For Cameroon I am interested in internet connections. Last time I set up Orange Wimax connections and I am particularly interested in Camtel and MTN's offerings.

Sun/Oracle OpenStorage - configuration

| | TrackBacks (0)
be1.png A Sun OpenStorage can be configured through a web interface or a command line (ssh).

In this article I'll focus on the web interface.

Initial configuration has to be done via the serial console and type

start /SP/console

The following screen just asks for primary network interface for management and the IP address.  After connecting the appliance through this interface the web interface on the left can be contacted (port 215 is standard).

After typing in username and password ("root" as user and "changeme" as password are the factory defaults) the "dashboard" appears:

OpenStorage: It rocks.

I'll write an article about configuration and possibilites of OpenStorage the next day(s), but as an appetizer here are two web configuration screenshots (click on them for original size):

First, the status dashboard, showing system/disk activity:


Our new OpenStorage arrived

| | Comments (2) | TrackBacks (0)
We just installed our new OpenStorage from Sun, consisting of an X7310 RAID (zfs) Storage Controller and a 4400 JBOD case (for SAS).

The X7310 has a 10 GE Ethernet card installed additionally, the lower half is filled with 11 1TB SATA disks and a 16 GB log flash device.

Sun OpenStorage appliances are special OpenSolaris versions installed with a web (and terminal) interface to configure ZFS file systems and block devices (ZVOL) to share them via iSCSI, NFS and CIFS to other SAN members.
