Hi, I am running centos6-5 on dell620 blades. mirrored local root drives several (including home) mounted filesystems.
The other blades are working fine. Top indicates the server is running 1% cpu, and very little memory (idleing) There is no error in the messages file There is no amber lights on the server.
When I log into my server it is fine, on my remote mounted home directory. When I cd to root (local disk) and I type ls it just hangs.
I ran top, the system is basically idle I ran ifconfig and everything looks good. when I ran df -h it hangs
when I run ls on my home directory it is fine when I run ls on my root directory it hangs when I run df -k it hangs
I can go into any remote mounted directory and everything works fine.
any suggestions.
Right off hand I would say that NFS is hanging and/or bad DNS lookup timeout.
Happened on several of our servers years ago.

The OP said the hanging issue is only impacting local filesystems, not network.

Did you check your logs and dmesg for interesting error messages?

On my messages, I only get that annoying nfs warning message that is common.
What is strange is it is the LOCAL ROOT filesystem
The NFS mounted filesystems work fine.
I was surprised that everything seems to work well on root as long as it is not looking at the root filesystem filesystem type commands like df -h or ls
Dell did a hardware diagnostic and said there is nothing in the hardware. Suggesting that I boot the server into single user mode and do a fsck on the root filesystem

update all firmwares to latest release?
sounds a bit like broken raid controller.
