NFS server is NFSV3 2.4.13 reiserfs 3.6 (also same error on 2.4.8pre4) NFS client is solaris8 We used to see this sort of error before the knfsd/reiserfs generation number patch. Now it has been showing up again a little bit. Questions: 1. IS this a solaris issue? I can go to another identical solaris box and it works. I reboot the linux nfs server and it still fails. Is Solaris NFS caching attributes wrong? Most of our sun boxes lack the latest solaris NFS patch 108727-08, yet our solaris boxes don't have confusion/trouble with sun or netapps nfs servers like this. 2. This solaris box sometimes mounts the linux NFS tree at different locations (via the automounter) -- /export/home and /export/home/subdir are both on the same linux filesystem, but will get mounted on the solaris box as /home/host1 and /home/special1 at the same time. Will that confuse things on the linux nfs server? eric Tcpdump looks something like this: (full tcpdump available) penett is the linux nfs server whitney is the sun nfs client ---------------------------------- 23:15:04.890730 whitney.3440783913 > penett.nfs: 108 getattr [|nfs] (DF) 23:15:04.890812 penett.nfs > whitney.3440783913: reply ok 112 getattr DIR 40775 ids 14397/61 sz 0 (DF) 23:15:04.905034 whitney.3440783930 > penett.nfs: 108 getattr [|nfs] (DF) 23:15:04.905061 penett.nfs > whitney.3440783930: reply ok 112 getattr DIR 40775 ids 14397/61 sz 0 (DF) 23:15:04.905538 whitney.3440783931 > penett.nfs: 120 readlink [|nfs] (DF) 23:15:04.905570 penett.nfs > whitney.3440783931: reply ok 116 readlink ERROR: Is a directory (DF) 23:15:07.006149 whitney.3440783952 > penett.nfs: 108 getattr [|nfs] (DF) 23:15:07.006179 penett.nfs > whitney.3440783952: reply ok 112 getattr DIR 40775 ids 14397/61 sz 0 (DF) 23:15:07.006602 whitney.3440783953 > penett.nfs: 120 readlink [|nfs] (DF) 23:15:07.006629 penett.nfs > whitney.3440783953: reply ok 116 readlink ERROR: Is a directory (DF) 23:15:07.596841 whitney.3440783955 > penett.nfs: 108 getattr [|nfs] (DF) 23:15:07.596869 penett.nfs > whitney.3440783955: reply ok 112 getattr DIR 40775 ids 14397/61 sz 0 (DF) 23:15:07.611629 whitney.3440783962 > penett.nfs: 120 readlink [|nfs] (DF) 23:15:07.611656 penett.nfs > whitney.3440783962: reply ok 116 readlink ERROR: Is a directory (DF)
