Solved Permission denied / Input/Output error - NFS ext storage [urgent]

[arnaudrigole]

Hi Fog community,

Sorry, its me again… my shcool project evaluation is next week and i still have a problem mouting an NFS storage node located on a windows server 2012R2.

I followed this procedure:
https://wiki.fogproject.org/wiki/index.php?title=Windows_Storage_Node
and i can’t pass the step “fog server” step which say i have to transfer local .mntcheck files on nfs server over NFS.

i can mount the @nfsserverIP:/images /images2
then cd /images2
then i try to cp or touch -> permission denied :(!!!

I run fog 1.2.
Can’t upload an image too, permission denied

FOG_TFTP user is “fog” with a pw i defined, same as the user on fog vm, same as the user defined on filezilla ftp server.

Sorry again for my poor english…!
can anybody help me?

@ch3i
Salut !
Ecoute ce matin ça fonctionne en upload/download, je ne sais pas comment.
J’ai toujours le message d’erreur “Device busy” à l’upload mais ça passe outre et ça fonctionne…

@Wayne-Workman
Still have the error, after redefined storage node

@Wayne-Workman
Yeah i’ve just recreated the fog storage node on webUI

@arnaudrigole Hi Arnaud.

Je peux t’aider au besoin en prenant la main, ce matin ou jeudi/vendredi.

also - don’t mount the NFS share to the fog server. we only did that to test if it was working or not.

This windows node is stand-alone. After the NFS share is set and FTP permissions set, and the needed files/directories created - ALL you have to do - is - create a new node in the fog Web Interface. That’s it.

Have you tried mounting the NFS from a client by hand? https://wiki.fogproject.org/wiki/index.php/Troubleshoot_NFS

Anyone know what can cause this problem? :s
I tried in “upload debug” task, it told me :

" Mouting file system … mount : mouting 192.168.253.20:/images/dev on /images failed : Device or resource busy

@Quazz
Of course, here it is :

“Management username” and “management password” are the same as defined for fog unix user, and as user with full rw rights on filezilla server

@arnaudrigole Could you post a screenshot of your storage node screen of the windows node from the FOG web UI?

@Wayne-Workman
Hi Wayne, Thanks for your help.
I will document it.

After we did the test windows “WindowsNode”, i recreated the “images” nfs share in E: no problem i have rw access mounted on linux.

… But still have error “Failed to mount NFS volume” when trying to upload, but no error message displayed ! “Mouting file system… done”

I still working on it.

@george1421 I helped via join.me and we ended up using that single powershell command of yours to setup NFS correctly on windows.

New-NfsShare –Name "windowsNode" –Path E:\ –Authentication sys -AllowRootAccess $True -EnableUnmappedAccess $True –Permission Readwrite

@arnaudrigole says he will document every step with the windows storage node. I look forward to what he comes up with.

@Wayne-Workman
Hi Wayne,
You gonna try with my environment? thats it ? tell me if u need everything.

[Wayne Workman]

Welp, I have time… I’m going to try this…

[arnaudrigole]

When i try to upload the image from my client, it say:

can’t chmod /images/@clientmacaddr : no such file or directory
/bin/fog.upload line 112 : /images/@clientmacaddr/d1.fixed_size_partitions : No such file or directory
/usr/share/fog/lib/partition-funcs.sh : line 66: /images/clientmacaddr/d1.original.fstypes no such files or directory…

I think its because the fog server has no rw rights again … but where !?!

[arnaudrigole]

Yeah i followed all the procedure more than 5 times…, each time i recreate a fog environment with 1.2 or trunk

i tried to access nfs storage on a windows machine with mount 192.168.253.20:/images * it works, but i have no rw access too ! ; it returns me :
Error 0x8007045D Input/output : same as linux!

Everyone + Anonymous access have total access on /images and /images/dev
NFS rights:

Did you follow all the steps? Because this is a permissions issue plain and “simple”.
