Just Did a simple Fedora 15 Alpha “minimal” Installation with btrfs as root Filesystem. Then I  did some checks and want to see if its really btrfs mounted:

[root@localhost ~]# mount
/proc on /proc type proc (rw,relatime)
/sys on /sys type sysfs (rw,relatime,seclabel)
udev on /dev type devtmpfs (rw,nosuid,relatime,seclabel,size=503504k,nr_inodes=125876,mode=755)

tmpfs on /var/run type tmpfs (rw,nosuid,nodev,noexec,relatime,rootcontext=system_u:object_r:var_run_t:s0,seclabel,mode=755)
tmpfs on /var/lock type tmpfs (rw,nosuid,nodev,noexec,relatime,rootcontext=system_u:object_r:var_lock_t:s0,seclabel,mode=775,gid=54)

hugetlbfs on /dev/hugepages type hugetlbfs (rw,relatime,seclabel)
mqueue on /dev/mqueue type mqueue (rw,relatime,seclabel)
[root@localhost ~]#

But it turns out that Fedora 15 added some more mounts Thats not really so userfriendly, how would it looks like with some more bind mounts or Filesystems ?

Great News, so SLES is maybe also usable wit Spacewalk.

I hope that Oracle will very soon support Red Hat Enterprise Linux 6 for his Database, so we also could start with tests there.

Red Hat Enterprise Linux 6 is out, at long last. Also IMHO lot of Code come from Fedora 13 not from Fedora 12 also there are lot of Kernel features from 2.6.32 until 2.6.34. The Release is pretty good beside some Problems with the Cluster we found ( it’s running but not really ready for Production ), hope they fix that very soon. Also certification is not there from the Major ISV’s.

Over 3.5 Years after RHEL5, RHEL6 came out. For me I think Red Hat will get into bigger Problems with the Major Releasecycle sooner or later. If they don’t Release a Major Release every 2 -max. 3! Years they don’t get the necessary Hardware update into they’re Kernel. From my side I don’t understand that they wait so long. So at the End the Releaseschedule for RHEL is complete not plannable from outside.Means also the ISV will have some Problems.

Also the Subscriptions have change significant ! http://www.redhat.com/rhel/purchasing_guide.html
Now you have to Subscribe per two – sockel ! also there are 3 diffrent Version for Virtual Guest inclusion. Then more or less all important packages are separate als Add-On ( don’t really understand what is where included )

–> conclusion we are back to RHEL 4 Times

Also the Add-On EUS has two variants EUS and ELS, where EUS extend the Lifecycle of a minor Release the ELS extend the Lifecycle of a Major Release ! BUT the exclusions are Big if you go to Site:

http://www.redhat.com/rhel/server/extended_lifecycle_support/exclusions/

http://www.redhat.com/f/pdf/RH_ELS_CustomerDatasheet.pdf

then you found out that Cluster and GFS for RHEL4 are not supported anyway –> How should buy such a ELS ? For which Server do I need a ELS ? Not for a Single Server, this I could maybe migrate.

Red Hat Enterprise Linux Server

Red Hat Enterprise Linux Server is sold on a per-socket-pair basis. This means the following prices are for every two populated sockets in the server. For example a 2-socket server with up to 1 guest and Premium support would cost $1,299/year, while a 4-socket server would cost twice that or $2,598.

Add-On Functionality

Optional functionality can be added to a Red Hat Enterprise Linux Server subscription. The following prices are in addition to the price of the underlying Red Hat Enterprise Linux Server subscription. The Add-On inherits the support of the underlying Red Hat Enterprise Linux Server subscription.

Fedora 14 is out now. They don’t include systemd right now, so the Bootprocess will stay with upstart.

First Time they will release also some Images on Amazon EC2.

After a few years of having a old Proliant ML370 Server with a Pentium III i decide to go with a AMD Athlon DualCore and install KVM for having some virtual Servers.

But there where some problems, as usual.

Since this early morning 2010-04-29 03:45 UTC looks like a Red Hat DataCenter ( PHX2 ) face a major outage ! Lot of Fedora Webservices are affected and also Red Hat themself with Bugzilla , German Website etc.

there is absolut no Infor on a Red Hat Site about this Problem.

see Fedora Announcement:

16 Cores und 256 GB Memory per Gast ist doch nicht zu verachten bei der neuen RHEV 2.2 ! Das ist einiges mehr als bei vielen anderen Lösungen wie Vmware 4.0 oder auch Citrix XenServer aber auch Microsoft Hyper-V ist noch nicht soweit.

Gutes Video zum Erklähren von Virtualisierung
