8 Looking into that I noticed, as you thought the gid of the share on
9 solaris is alphabetic wheel but numeric 15. Which is the gid of
10 `man' on gentoo.
11
12 But I noticed the gid 16 is not taken on the gentoo os so promoted man
13 to gid 16 and changed wheel from 10 to 15.
14
15 Logging my user out and back in I see the gid 15 now is wheel so the
16 same as solaris.
17
18 Having my user mount the nfs ... it ends up `reader:wheel'. Both are
19 my users uid and one of his gids so now both the uid and gid match
20 those on the solaris OS where user reader:wheel owns the source
21 directory. (also /projects on solaris box).
22
23 But with all that in place.... a copy using `-a' still causes the the
24 same error warning.
25
26 ls -l /projects/it
27 -rw-r--r--+ 1 reader wheel 0 Jul 27 09:17 /projects/it
28
29 cp -a /projects/it /projects/it2
30 cp: preserving permissions for `/projects/it2':
31 Operation not supported
32
33 ls -l /projects/it2
34 -rw-r--r--+ 1 reader wheel 0 Jul 27 09:17 /projects/it2

36 ==============================================
37
38 user reader (on gentoo) running command id -a
39 uid=1000(reader) gid=1000(reader) groups=15(wheel),16(man),
40 250(portage),1000(reader)
41
42 user reader (on solaris) running command id -a
43 uid=1000(reader) gid=10(staff) groups=10(staff),3(sys),4
44 (adm),15(wheel)
45
46 ==============================================
47
48 And the nfs source directory is also set-gid (by user reader)
49 ls -ld /projects (on solaris server)
50 drwxr-sr-x 14 reader wheel 17 2009-07-27 09:29 /projects
