It's nice to know other folks have the same problem I do, except mine was on a honkin' Dell R730 server with lots of cores and memory. Btw, folks, the normal update installs teh "with debugging" as an option; I *assuem* that it has crash kernel enabled. However, /etc/kdump.conf is default configured to dump to /var/crash, which has nothing at all in it. Also - I believe I mentioned it, it kernel panics *just* as it tries to switch root. Diego, can you tell if you're getting a kernel panic? mark ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

[CentOS] nfsvers and nfs-utils-1.3.0-0.48.el7
We encountered a weird problem today, and I thought some of you might like to hear the solution. The underlying change was listed in the 7.4 changelog, so it's not a bug, but it may drive you buggy. The majority of our HPC cluster nodes run CentOS 7, though the exact patch levels vary from node to node. None is older than 7.3, but a few newer nodes were kickstarted right to 7.4. The problem was that our mounts of Isilon NFS exports were failing randomly among the nodes. Routing was fine. Network connectivity was fine. The short answer is that the default in 7.4, and I think in the nfs-utils-1.3.0-0.48.el7 package in particular, has changed. While NFS v4.0 was the default up to 7.3, the 7.4 protocols are subtly different: 1. Try NFS v4.1 first 2. Fail down to NFS v3 3. Fail down to NFS v2 The problem is that our Isilon works with NFS v4.0, not 4.1, but 4.0 is not in the fail-down path. The short-term answer is to specify nfsvers=4.0 in our autofs configuration files, which works like a charm. Like I said, this was an announced change, but the implications escaped us until now. So this little writeup is just for the record. -- Paul Heinlein heinl...@madboa.com 45°38' N, 122°6' W ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

I was thinking the OP's situation was /boot is a reasonable size but just got filled up because it was not being monitored. And, as a result, he made yum sad. So now all he wants is to clean it up just enough to use other stuff, and then as mentioned before reconfigure grub2.cfg to keep only a couple of 3 kernels around.

I need to know if there is an easy way to increase my /boot partition. When I installed CentOS 6 after running 5, it was my oversight not to increase the /boot size. it's too small and I can't do yum updates. if it's not easy to actually increase it, is it safe to take a chunk in my root filesystem (like /new.boot or something) and just mount it as /boot from now on so it uses the space or is that not a good idea? I am sure I could easily copy the rpms/kernel stuff over to it and then unmounts the real /boot and mount this new area as /boot. Can you administrators let me know what you think of all this? Thanks in advance. Hi, Since a lot of people seem to say none of the above can be done, I'm starting to feel slightly unsure, but I though gparted could extend, shrink and move partitions while preserving data. You would be asking gparted to: 1. Reach inside an LVM PV and shrink one filesystem and its LV, 2. Rearrange the extents inside the PV to make free space at the beginning, 3. Move the start of the PV and adjust all of the starting offsets for the LVs, 4. Finally, enlarge partition 1 into the freed-up space. Even if gparted was willing to attempt that, there is no way I would trust it to do it correctly. Quite. I'd never try this without a backup, of course. In fact, I've only ever used gparted in situations where I had a system dump already. Still, it could save you from a bit of work, as in, if it does succeed, you won't have to do a full recovery. Also, I'm not really sure about the state of the LVM support, now that you mention it. (But there is supposed to be *something* in that area.) - Toralf ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Surely you do realize there are SEVERAL other display options besides just the video console, right? You can use kdump, you can use a serial console .. you can use google and the search term 'capture kernel oops' to get more than 10 full search page results on how to capture the output of a kernel oops. signature.asc Description: OpenPGP digital signature ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
