[PVFS2-users] trying CVS version of Oct 1. (was: problem with multiple mount points)

[Andrew Pochinsky]

I tried and built a PVFS2 from CVS on x86-64, here are impressions and 
complains:

1. Setup: dual Xeon processor machine running SLES9 with 2.6.5-7.97.smp 
kernel from the distribution.
     Existing pvfs2 file system on 6 servers arranged into three fs:
          fsA0 at /data/0, 5TB on fs00 (meta + data)
          fsA1 at /data/1, 10TB on fs01 (meta + data) and fs02 (data)
          fsA2 at /data/2, 15TB on fs03 (meta + data), fs04 (data) and 
fs05 (data)
2. The sources built almost clean, there were a few warnings about 
using int and unsigned formats for size_t arguments, just to be safe, I 
went through the sources and casted the arguement to int in all cases.
3. pvfs2-server started fine with the old configs on all servers.
4. Utilities programs (pvfs2-ping, pvfs2-statfs, pvfs2-cp and pvfs2-rm 
were tested) work fine with multiple pvfs2 mounts. The only complaint 
is that pvfs2-ping and pvfs2-statfs (I did not check other programs) do 
not like the situation when some of the servers listed in pvfs2tab are 
not running - in a situation when  servers for fsA2 are down both 
programs complain about this when ran with -m /data/0 or -m /data/1
5. The kernel module pvfs2.ko does not load. dmesg shows the following 
error:
pvfs2: Unknown symbol pvfs2_permission
This prevents test of pvfs2-client and fs operations.

Hope it helps,
