comment Automatically check for Security Updates on CentOS or Scientific Linux?
Bert: It DOES not work on CentOS, CentOS reporting 0 security updates is not to be relied on. Ever.

comment Reloading a kernel “live” in CentOS / RHEL 6
kexec was mostly aimed at industrial linux systems and got prominent via carrier gracde linux project. those are specialized / hardened distros for professionals and half-ass desktop/server distros like RHEL (for years) didn't make full use of kexec. OpenSUSE started like 3 years ago to skip the reboot after installing the OS. now in RHEL7 you can actually do it, too. I hope this kind of explains why kexec might have been there for 10 years but you couldn't just "use" it to do the 'fast reboot' it was intended for.

comment How can I validate a ZFS snapshot image residing on a backup system?
You taught me two things in one post. Validating a zfs dump and storing a ftp file into a pipe. I'll remember this day long after forgetting how to do either :)

comment How do I disable autovacuum on Postgres 8.1.22?
upvoted question since the answers are so inconclusive useless. vacuum full was the right measure at 8.1 for the task and he'd not need to run a loop killing autovacuum if it wasn't still being enabled. he also said he's in progress of migrating to a new version at that exact time. learn to read please.

comment What causes repeated linux NFS client side RPC credential refreshing?
iirc noac also just concerns credential caching, so writes to permission metadata are immediate, no "writes". Didn't edit since i'm not all sure now.

comment How to find the physical volume(s) that hold a logical volume in LVM
One thing, it doesn't work with lvm mirrors enabled. There it'll just show "lvname_rimage0,lvname_rimage1" instead of the underlying disks. (not your fault, the command and the mirroring itself is badly designed). Even then it's still good to spot unmirrored lv's. Just be careful not to fully rely on the output because the above.

comment Best compression for ZFS send/recv
Thanks a lot for this post. Looking at zfs send more closely I very quickly got the feeling that it has a bad behaviour (aka "design") when sending to a latency-bound target. After about a dozen results telling that zfs can't possibly ever be to blame for anything. I am very grateful you took the time to look into it and posted your results.

comment What causes repeated linux NFS client side RPC credential refreshing?
the readdirplus issue has caused issues to many people, it is incredibly stupid design to turn off the feature when it's most needed. But as to the issue, I think this is caused by either "noac" or wrong "actimeo" settings.
