The amanda users also need rx on the directory.

Any ideas? Perhaps this is a NFS/NETAPP problem more than a AMANDA

Any ideas as to what > I'm doing wrong? The OS is Ubuntu Linux 7.04. Thanks all! Are you running into the "root_squash" problem? Root on the client is normally mapped to the user "nobody" on the server. And that user "nobody" is probably getting the "permission denied" error when trying to access the directory.

Re: Amanda 2.5.1p3 gnutar permissions trouble
No, no automounters. Here is the amcheck failure when trying to access a directory underneath the mount point: Amanda Backup Client Hosts Check ERROR: tardis: [could not access /tfs/common/backups (/tfs/common/backups): Permission denied] Client check: 1 host checked in 0.019 seconds, 1 problem found and an excerpt from that debug file: OPTIONS features=feff9ffeff7f; ERROR [could not access /tfs/common/backups (/tfs/common/backups): Permission denied] And the successful amcheck when trying to backup the entire mount point (/tfs/common): Amanda Backup Client Hosts Check Client check: 1 host checked in 0.019 seconds, 0 problems found /tfs is on the local system, and /tfs/common (and everything underneath that) is NFS mounted from our NetApp filer.

Amanda 2.5.1p3 gnutar permissions trouble
Hi fellow users :) I'm running into a problem with permissions when backing up a nfs mount. I'm using gnutar, and while I can backup the entire mount just fine, if I try to put just a subdirectory of the mount in the disklist, I get "Permission Denied" errors from amcheck and amdump. Any ideas as to what I'm doing wrong? The OS is Ubuntu Linux 7.04. Thanks all! Jordan
