Here's the call that's failing: lstat("../lib/libts_variance-0.0.so.0", 0xbffffb98) = -1 EIO (Input/output error) It seems that sometimes I can provoke it 4 or more times in a row, other times no matter how hard I try, I can't. "4 times in a row" here means umounting and then remounting the export on the assabet. As I mentioned in my last (private) mail, the setup was slightly different from my first description. flint (nfs client) is responsible for writing these files onto the NFS server (raistlin), and the programs are run on assabet (nfs client). flint ----- kernel 2.2.18-cdhs (raid) mount indicates: raistlin:/usr/src on /net/raistlin/src type nfs (rw,rsize=4096,wsize=4096,addr=192.168.0.3) raistlin -------- kernel 2.4.16 universal NFS server 2.2beta48 raistlin's exports file looks similar to the following: /usr/src flint(rw,no_root_squash) /usr/src/v2.5 assabet(ro) assabet ------- kernel 2.5.1-pre10 mount indicates: raistlin:/usr/src/v2.5 on /usr/src/v2.5 type nfs (ro,nolock,addr=192.168.0.3) -- Russell King (rmk@arm.linux.org.uk) The developer of ARM Linux http://www.arm.linux.org.uk/personal/aboutme.html
