experiences with zpool errors and glm flipouts
...data from UFS slice to zpool.
Then I tried to attach the UFS slice to the zpool, in order to
form a mirror. The resilver kicked off but eventually ground my
machine to a halt (the last I saw was 77% completed), and I was getting
a ton of these errors:
scsi: WARNING: /pci at 1d,700000/scsi at 4 (glm0):

Cross-validation in R
...f 0.02184. The means are similar but SD are
different.
Questions are:
(1) how the $delta is computed in the cv.glm? In the home-made version, I
simply use ((Yobs - Ypred)^2)/n. The equation might be correct because the
mean is similar.
(2) in the cv.glm, I have the impression the system is using glm0.dmi that
was generated using all the data points whereas in my homemade version I
only use the "test" database. I am confused if the cv.glm generates new glm
models for each simulation of if it uses the one provided?
(3) is the cv.glm sampling using replacement = TRUE or not?
Thanks in...

zpool kernel panics.
Hi Folks,
I''ve got a 3.9 Tb zpool, and it is casing kernel panics on my Solaris
10 280r (SPARC) server.
The message I get on panic is this:
panic[cpu1]/thread=2a100a95cc0: zfs: freeing free segment
(offset=423713792 size=1024)
This seems to come about when the zpool is being used or being
scrubbed - about twice a day at the moment. After the reboot, the
scrub seems to have
