attempt to access beyond end of device XFS Disks
by Götz Reinicke - IT Koordinator 05 Jul '17

05 Jul '17

Hi, I rebooted some CEPH servers with 24 HDs and do get some messages for some of the disks: [ 519.667055] XFS (sdk1): Mounting V4 Filesystem [ 519.692307] XFS (sdk1): Ending clean mount [ 519.781975] attempt to access beyond end of device [ 519.781984] sdk1: rw=0, want=1560774288, limit=1560774287 All disks are xfs formated and currently I don't see any problem on the CEPH side. But I have a bad feeling. I updated the kernel too from kernel-3.10.0-514.21.1 to kernel-3.10.0-514.26.1, … [View More]

System Start-Up Issue Progress
by Chris Olson 04 Jul '17

04 Jul '17

My thanks to all that responded to my posting about our virtual machine CentOS 6 system start-up issue. I found the alternative boot options to be the most helpful. Interrupting the boot-up process with Alt-d or Escape allowed me to see what appears to be a quite normal string of start, install and mount activity. However, this process ends with the system hanging at the point below: Starting ipmidetectd: ipmidetectd: No nodes configured [FAILED] Starting sendmail: It is … [View More]

Physically moving a mail server vs. cached DNS
by Nicolas Kovacs 03 Jul '17

03 Jul '17

Hi, I just moved my main mail account and web content from a low-cost (low-quality) provider to my own root server running CentOS 7. I transferred the domain name from DNS management to my registrar, configured BIND, Apache, Postfix, Dovecot, NTP, SELinux, etc. Now things are running rather nicely. One thing is puzzling me though. The updated mail server DNS seems to have spread around so far. $ host -t mx microlinux.fr microlinux.fr mail is handled by 10 mail.microlinux.fr. Unfortunately, … [View More]

AMD Ryzen and CentOS
by Yves Bellefeuille 03 Jul '17

03 Jul '17

I have a new system with an AMD Ryzen 1600 CPU and I'm trying to run CentOS, so far without success. The only information I could find was a post reporting that CentOS 7 would crash during installation on a Ryzen system: https://www.centos.org/forums/viewtopic.php?t=61831 . I tried updating to the latest elrepo "mainline stable" kernel, version 4.11 (by booting from a live CD and using chroot to enter CentOS: that worked), but the system still doesn't work properly. I'm using CentOS 6 but I'… [View More]

rsync and cause/source of an empty file
by James B. Byrne 01 Jul '17

01 Jul '17

We transfer files from a VAN provider at 15 minute intervals using rsync over ssh. The setup is somewhat complicated in that the VAN will not permit direct rsync access and so we establish the link via sshfs and then mount remote location as local. My question is, given the above conditions and the following rsync command: /usr/bin/rsync --chmod=o+r --chmod=g+w --itemize-changes --remove-sent-files --times /var/spool/imanet/pick_up/* /var/spool/imanet/drop_off Under what circumstances … [View More]
