Description Jay Fenlason 2005-04-22 21:08:45 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.4) Gecko/20050318 Red Hat/1.4.4-1.3.5

Description of problem:
The default mode for tape devices is 640 root:disk.  Amanda expects non-root users in group disk to be able to read and write the tape devices.  After each reboot I have to manually chmod 666 /dev/*st[0-9]*

Version-Release number of selected component (if applicable):
udev-057-2

How reproducible:
Always

Steps to Reproduce:
1.Configure amanda
2.Attempt to run amcheck or amdump
3.
  

Actual Results:  amcheck, amdump, etc report Permission Denied when they attempt to access the tape device.

Expected Results:  amcheck, amdump, etc can read and write the tape device.

Additional info:

Also, whenever I modify /etc/udev/rules.d/50-udev.rules to make the tape devices writable, my changes are blown away the next time "yum update" updates the udev rpm.  Perhaps the file should be %config(noreplace).

Comment 1 Harald Hoyer 2005-04-25 12:29:12 UTC

I will change the permissions. Why don't you create
/etc/udev/rules.d/10-local.rules or /etc/udev/rules.d/60-otherlocal.rules?

Comment 2 Jay Fenlason 2005-04-25 13:14:36 UTC

I couldn't find any reference to those files in the man pages, nor in the 
comments in the files under /etc/udev/  Would entries in those files (-local 
or -otherlocal) override the entries in 50-udev.rules?

Comment 3 Harald Hoyer 2005-04-25 15:27:54 UTC

you should add your own rules in files in /etc/udev/rules.d with the extension
.rules and /etc/udev/permissions.d/ with the extension .permissions.

man udev:



       udev_rules
              The name of the udev rules file or directory to look for  files
              with  the  suffix  .rules.   All rule files are read in lexical
              order. The default value is /etc/udev/rules.d/.

       udev_permissions
              The name of the udev permission file or directory to  look  for
              files  with  the suffix .permissions.  All permission files are
              read in lexical order. The default value  is  /etc/udev/permis-
              sions.d/.

Comment 4 Jay Fenlason 2005-07-13 13:52:27 UTC

Rawhide is still creating /dev/nst0 as mode 640 with udev-058-2.

Comment 5 Harald Hoyer 2005-08-02 15:25:58 UTC

ok... what about udev-063-4?

Comment 6 Chris Hapgood 2005-09-23 19:12:45 UTC

To get by, I added the following entries in a file named /etc/udev/rules.d/60-
tapedrive.rules:

KERNEL=="ht*",                  GROUP="disk",   MODE="0660"
KERNEL=="nht*",                 GROUP="disk",   MODE="0660"
KERNEL=="pt[0-9]*",             GROUP="disk",   MODE="0660"
KERNEL=="npt*",                 GROUP="disk",   MODE="0660"
KERNEL=="st*",                  GROUP="disk",   MODE="0660"
KERNEL=="nst*",                 GROUP="disk",   MODE="0660"
KERNEL=="osst*",                GROUP="disk",   MODE="0660"
KERNEL=="nosst*",               GROUP="disk",   MODE="0660"

Comment 7 Harald Hoyer 2006-02-15 12:22:03 UTC

should be this way in the latest udev releases.
