So to begin with, there is a need to figure why in your case the f5d2f7c6-093f-46d6-a844-224d92db5ef9 folder is not to be found on the nfs storage mounted on that node, which should be there as far as I understood since this is the same nfs mount path and server shared between all hosts which are connected to this SD. Maybe compare the mount options between the working nodes to the non-working node and check the export options on the nfs server itself, maybe it has some specific client ip exports settings? > Regards, > > Jorick Astrego > > > > > Met vriendelijke groet, With kind regards, > > Jorick Astrego > > *Netbulae Virtualization Experts * > ------------------------------ > Tel: 053 20 30 270 [email protected] Staalsteden 4-3A KvK 08198180 > Fax: 053 20 30 271 www.netbulae.eu 7547 TA Enschede BTW NL821234584B01 > ------------------------------ > >
