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.

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

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

    update all firmwares to latest release?

    sounds a bit like broken raid controller.
