Re: [zfs-discuss] After update to S11, zfs reports some disks as 'corrupted data'

Phew… seems that the S11 update process replaced my modified qlc.conf 
with a standard one. In SE11 I had to lower the queue depth by setting 
max_execution_throttle to something lower than 16. Mostly since I am 
exposing 16 LUNs from each storage and this the qlc.driver flooded the 
storage controllers with I/Os.


Cheers,

[zfs-discuss] After update to S11, zfs reports some disks as 'corrupted data'

2011-11-19 Thread Stephan Budach 

Hi all,

I am in the process of updating my SE11 servers to S11. On one server I 
am having two zpools made out of mirror vdevs and up to now none of 
these zpools have shown any error.


However, after updating to S11 three disks - and unfortuanetly two of 
the same miorror vdev are shown as UNAVAIL due to 'corrupted data':


  pool: obelixData
id: 9610325806378085846
 state: UNAVAIL
status: One or more devices contains corrupted data.
action: The pool cannot be imported due to damaged devices or data.
   see: http://www.sun.com/msg/ZFS-8000-5E
config:

So I reverted back to my saved SE11 BE and SE11 shows these disks as 
online and imnports this zpool without any issue.
I have now a scrub running on this zpool, but I am curious, if anyone 
had ever experienced something similar.


Thanks,
budy
