I can understand that behavior in a shutdown situation. But I'm surprised that unmounting (either cleanly or uncleanly) one of two exported filesystems triggers the NFS service to shutdown completely. Is this consistent with other peoples experiences? ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
[CentOS] NFS shutdown issue
Hi all, I have an odd interaction on a CentOS 7 file server. The basic setup is a minimal 7.x install. I have 4 internal drives (/dev/sd[a-d]) configured in a RAID5 and mounted locally on /data. This is exported via NFS to ~12 workstations which use the exported file systems for /home. I have an external drive connected via USB (/dev/sde) and mounted on /rsnapshot. I use rsnapshot to back up the RAID5 to the external drive periodically. I also export /rsnapshot (read only) to the workstations so users can grab a backup copy of /home data if needed. These two mounts (/data and /rsnapshot) should be independent of each other. However, a couple of times now I've had somebody accidentally unplug my backup drive (sde), which causes NFS to shut down. Here are the messages entries when this happens. Oct 28 16:34:12 linux-fs01 kernel: xhci_hcd :00:14.0: Cannot set link state.

Re: [CentOS] Radeon graphics problems with CentOS 6.6
I thought about trying centos 7. But in the end that doesn't really help me since I'm trying to keep my current centos 6 installation working. I don't really have the time/energy to reinstall everyting under CentOS 7 right now. I was able to get a 6.6 LiveCD built myself. The liveCD has the same problem - X doesn't work. I can boot the "Basic Video" option from the LiveCD and I can at least get to the desktop but there are several odd video problems when I do that. But I think that means that there is a genuine problem with Xorg on my hardware. Does anyone know who I should submit this bug to - AMD or Xorg?

Re: [CentOS] Radeon graphics problems with CentOS 6.6
I'm still struggling with this. I was hoping to boot a centos 6.6 livecd to see if this is specific to my installation or a general problem with my hardware. I can't find a 6.6 livecd on any of the several mirrors I've checked or on the centos vault. Does anyone know if one is available somewhere. Other ideas are welcome too. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

When I boot a 6.6 kernel with the fglrx driver, my machine completely locks up. with the stock ATI driver X would lock but I could still ping/ssh to the machine. I can still boot using the fglrx driver with a 6.5 kernel (but performance seems worse than before...).

[CentOS] Radeon graphics problems with CentOS 6.6
Hello, I saw in the CentOS 6.6 release notes that the Xorg ABI has changed but that "This should not concern anyone who uses the default drivers shipped with CentOS." I'm using the ATI drivers in Base but X still fails when I boot a CentOS 6.6 kernel. I was hoping this is a known problem that would get fixed with a kernel update but I'm still having problems with the 2.6.32-504.1.3.el6.x86_64 kernel. Relevant info below. Any ideas?
