Maybe it's a good idea to upgrade those arrays with older metadata before doing the 7.6 upgrade.

But if not, the log should contain something useful. I like the hypothesis about mdadm metadata version 0.9, however that's still really common on RHEL and CentOS. It was used for /boot prior to about Fedora around Fedora 24 maybe? It could also be a dracut bug, since that's what's largely responsible for assembly. But then it can be confused by a change in udev rules. :-D However, going back to mdadm 0.9 metadata, that version should only be kernel auto detected. Theoretically, it gets activated before dracut gets involved. 1.x versions have no kernel autodetect, instead it happens in dracut (by calling mdadm to assemble and run it). Oh, is this really dm-cache, not lvmcache? That might be a source of confusion, if there isn't lvm metadata present to hint at LVM for proper assembly. Of course, lvmcache still uses device mapper, but with LVM metadata. Anyway is quite an interesting, and concerning problem.

Often there will be a kernel stack trace that provides hints as to which module was handling the interrupt, and therefore which device or driver is at fault. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

How much memory do the systems have, what is its CPU, and how many packages are you installing? [The Dell Optiplex 330 is from 2007 and came with several different layouts so it might need info.] Finally does the install work if you only choose what the minimal would install? > Cheers, > > Niki > -- > Microlinux - Solutions informatiques durables > 7, place de l'église - 30730 Montpezat > Site : https://www.microlinux.fr > Blog : https://blog.microlinux.fr > Mail : i...@microlinux.fr > Tél. : 04 66 63 10 32 > ___ > CentOS mailing list > CentOS@centos.org > https://lists.centos.org/mailman/listinfo/centos -- Stephen J Smoogen. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
[CentOS] Weird problems with CentOS 7.6 1810 installer
Hi, I just updated my installation media for CentOS. I have a few sandbox PCs in my office, and I'm testing CentOS 7.6 1810 on them. There seem to be a few issues with the CentOS 7.6 1810 DVD. Checked DVD integrity on startup : OK. First attempt : installer froze on root password dialog. Second attempt : installer froze on dependency calculation. Third attempt : installer froze on network interface definition. Similar behavior on two different machines. On the same machine, the minimal DVD seems to work OK. I could manage to switch to another virtual console, and I have the following kernel log messages: WARNING: kernel:perf: interrupt took too long Any idea what's going on here? I should add that all the previous CentOS 7 installation DVDs worked perfectly on these PCs (Dell Optiplex 330).
