Re: Getting "mount error 5 = Input/output error"

Hi,

I have had some issues in the past with mds and the error 5.

Try to include the ip/hostname in your mount statement also.

I normally crosscheck these points:
 - Doublecheck you can read the auth file and you have the right version of ceph.
 - Check dmesg for any pointers.
 - Make sure you don't have any lingering mounts somewhere using an older version and/or pointing to the wrong monitors (ceph mount points to monitors not! where mds is installed)
 - I've had some bad experience with stock kernel 3.13 and mds - and usually upgrade to 3.16 lts. You should be able to mount everything fine on 3.13 still though.

Cheers,
Martin

Hi,

I just started learning Ceph. I would appreciate your help now and in the future. 
I was attempting to  create a mount point to mount the Ceph File System.
I’m getting the above error message while running Ceph in Ubuntu (guest-VM, with allocated 4GB RAM and 30GB Storage) in MacBookPro with total 8GB RAM. 
My command  [ sudo mount -t -o name=admin,secretfile=./asecret daisy:/mnt/cephfs ] just sits there for a long time and then gives the error 
[ "mount error 5 = Input/output error"] as STD output. 

BTW, all three OSDs are up-n-running, though !
I would appreciate any help.

Thank you and best regards,
-Deb
