Centos 7, grub2-mkconfig, unsupported sector
by m.roth＠5-cent.us 02 Jan '16

Hi, folks, Well, I get back from vacation, and three CentOS 7 boxes didn't come up this morning (my manager and the other admin did the update & reboot). On these three - but *not* another one or two, and I don't think those others are Dells, they're supermicro's - the 327 kernel fell into the rdosshell, I guess. I finally got one the three up by going back to the 228.14 kernel. Now, after googling and finding the CentOS bugzilla, 0009860, that referenced the upstream bugzilla, I applied the workaround discussed in it, Adding initcall_blacklist=clocksource_done_booting to GRUB_CMDLINE_LINUX in /etc/default/grub and then grub2-mkconfig -o /etc/grub2.cfg" On one. On the other, that's got a *large* RAID appliance (a JetStor w/ 42 4TB drives...), it seemed to work... then gave me a dozen or so ERROR: unsupported sector size 4096 on /dev/sdd. ERROR: unsupported sector size 4096 on /dev/sde. 0. Did the grub2-mkconfig actually work correctly? 1. Is it safe to ignore the errors and reboot? 2. This seems to be an old bug in os-prober, that was fixed years ago - has it slipped back in? mark

I just updated my fileserver to version 7.2 and got some NFS problems after that. In /etc/exports I have the following line /path hostname(ro,insecure) Now that host can no longer mount that share. I get mount.nfs: access denied by server while mounting x Also when I do restart of the NFS server I get following in the logs Dec 30 21:59:33 files systemd[1]: Starting NFS server and services... Dec 30 21:59:33 files nfsdcltrack[31076]: sqlite_query_reclaiming: unable to prepare select statement: no such column: has_session Dec 30 21:59:33 files polkitd[28879]: Unregistered Authentication Agent for unix-process:31032:12640806 (system bus name :1.635, object path /org/freedesktop/PolicyKit1/AuthenticationAgent, locale en_GB.UTF-8) (disconnected from bus) Dec 30 21:59:34 files nfsdcltrack[31412]: sqlite_insert_client: insert statement prepare failed: table clients has 2 columns but 3 values were supplied What to do?
