I typically do a backup via rsync of my home directory to a backup directory on another machine. That backup directory is mounted as an NFS mount on my machine. I run the backup through cron as a job executed through /etc/cron.daily. Normally, all goes well, and I get a daily email detailing what was backed up, etc.
Yesterday, I upgraded mount and nfs-* (nfs-common, nfs-kernel-server) on the client. Today, my backup failed on most of the files it tried with permissions issues ("permission denied (13)"). I upgraded the server to the most recent mount and nfs-* in unstable. mount is now 2.13.1.1 and nfs-* are 1.1.4-1. No changes to /etc/exports on the server, no changes to /etc/fstab on the client. Both client and server have the same versions of these packages. I umounted the directories on the client, umounted them on the server, brought nfs-* down, back up, remounted the directories on the server and then on the client. No problems with mounts. To test this permissions issue, I decided to narrow the parameters: copy one file from my home directory to the backup directory. This file didn't exist on the backup directory. I tried copying the file both as root and as myself (paulf). Same permissions problem in both cases. Here is the transcript (as root): sherman:/home/paulf# cp .0verkill /lan/backup/backup/sherman/home/paulf/ cp: cannot create regular file `/lan/backup/backup/sherman/home/paulf/.0verkill': Permission denied Here is the file: -rw-r--r-- 1 paulf paulf 17 2007-11-06 23:38 .0verkill Here are the permissions on the directory being copied to: sherman:/home/paulf# ls -l /lan/backup/backup/sherman/home total 8 drwxr-xr-x 135 paulf paulf 8192 2009-01-13 10:14 paulf Here is the relevant content in the client's /etc/fstab: pokey:/lan /lan/backup nfs soft,intr,timeo=12,wsize=8192,rsize=8192 0 0 Here is the relevant content in the server's /etc/exports: /lan sherman(rw,sync,no_root_squash) So, effectively, root *is* being squashed, and even as the owner of the file I (paulf) can't do the copy. Any help would be appreciated. Paul -- Paul M. Foster -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
