[sles-beta] few things to note after my first install

[Decker Maximilian]

Dear SuSE,

please, any official comment on why there is no ext4 support in SLES 11, even in SP3 ? This question is asked quite a lot 
by our customers, and I am running out of arguments here. Especially when it comes to "but in RHEL there is .... "
To some degree I could understand that for 11, it was missing from the beginning. But what are the odds that we see ext4 in 12 ?

Btw - you know that reiserfs (v3) has some serious stability issues as of post-2.6.35 kernels, right ? The BKL replacements 
somehow rendered reiserfs prone to deadlocking in a more or less frequent manner. These issues seem to exist up to at least
the current 3.8 kernels. So (in theory) also SLE >= SP2 (i.e. 3.0.x) kernels might be affected. 
But the good thing is - I cannot tell for sure as none of our maintained SLES 11 installations is on reiserfs. (same with btrfs)

However, anything regarding ext4 would be highly appreciated.


thanks

- Maximilian

To add to that, we can't/won't be able to use BTRFS until it can support /boot.  Our SLES11 deployment model is based on using Atomic updates, which requires the first 2 partitions to be dedicated to Atomic.  So, that means that /boot is therefore incorporated into the root partition.  The ability to roll back patches and upgrades is critical, but not being able to roll back a kernel makes BTRFS useless for us.  Just my 2cents worth from the field...

Hi list,

regarding the lack of (supported) ext4, just out of curiosity - what exactly is SuSE's reason behind obviously abandoning ext4, which by now is a well known, fast and proven evolution to ext3 ?

Of course, BTRFS really is the cool new stuff, and it seems like it will become an amazing alternative. But to be honest none of our SLES customers is actually running BTRFS in their datacenters yet.
Some lab or testing installations do exist, though, however bottom line is - for production systems we are effectively stuck with ext3.
(sometimes even due to missing support from 3rd party SW vendors)

If I understand correctly ext4 might also be missing in SLES 12.
And I know there are plenty of discussions on this matter all around the internet, but hey, I hope with the current Beta maybe SuSE can shed some official light on that. Really would be great to know.

Please don't get me wrong, I know there are quite a bunch of brilliant developers at SuSE that are giving their blessings to the current state of BTRFS, and we also got official SuSE support on that, but it just does not help "in the field".... people still consider it beta.


thanks,

- Maximilian
