The special feature is IBM has dfs. I guess it is normal but the dfs file system at IBM starts out with /.../path/to/files When I open a file, emacs hangs for a long time. I put in some fprintf's into file-exists-p (dbx told me that is where I was hanging). The output looks like this: stat for '/.../austin.ibm.com/fs/projects/aix/aix52Q/{arch}/=tagging-method' stat for '/.../austin.ibm.com/fs/projects/aix/{arch}/=tagging-method' stat for '/.../austin.ibm.com/fs/projects/{arch}/=tagging-method' stat for '/.../austin.ibm.com/fs/{arch}/=tagging-method' stat for '/.../austin.ibm.com/{arch}/=tagging-method' stat for '/.../{arch}/=tagging-method' stat for '/{arch}/=tagging-method' ...snip... stat for '/.../austin.ibm.com/fs/projects/aix/aix52Q/MCVS/CVS' stat for '/.../austin.ibm.com/fs/projects/aix/MCVS/CVS' stat for '/.../austin.ibm.com/fs/projects/MCVS/CVS' stat for '/.../austin.ibm.com/fs/MCVS/CVS' stat for '/.../austin.ibm.com/MCVS/CVS' stat for '/.../MCVS/CVS' stat for '/MCVS/CVS' This is for a single open. I removed some (many) lines. The killer are these two stats: stat for '/.../MCVS/CVS' stat for '/.../{arch}/=tagging-method' With IBM's dfs set up, these each hang for quite some time (minutes). I discovered vc-ignore-dir-regexp I changed it to be this: ## this is from my custom-set-variables in my init.el file (vc-ignore-dir-regexp "\\`\\([\\/][\\/]\\|/\\.\\.\\./\\|/net/\\|/afs/\\)\\'") As you can see, I added /.../ into the pattern. This seems to be exactly what I need. Now the stats look like this: stat for '/.../austin.ibm.com/fs/projects/aix/aix53H/{arch}/=tagging-method' stat for '/.../austin.ibm.com/fs/projects/aix/{arch}/=tagging-method' stat for '/.../austin.ibm.com/fs/projects/{arch}/=tagging-method' stat for '/.../austin.ibm.com/fs/{arch}/=tagging-method' stat for '/.../austin.ibm.com/{arch}/=tagging-method' ...snip... stat for '/.../austin.ibm.com/fs/projects/aix/aix53H/MCVS/CVS' stat for '/.../austin.ibm.com/fs/projects/aix/MCVS/CVS' stat for '/.../austin.ibm.com/fs/projects/MCVS/CVS' stat for '/.../austin.ibm.com/fs/MCVS/CVS' stat for '/.../austin.ibm.com/MCVS/CVS' I thought this might be a good general change to add in. The pattern already has afs in the list. I believe this is the dfs equivlalent. Although I have not been bit by it yet, I might need to add in /gsa/ as well for the gsa file system. It has the same pattern: /gsa/region/path/to/file So, probably stat of /gsa/CVS/ is going to hang (although from the command line it does not seem to). I hope this makes it to the list. I don't know if I am signed up from this email address or not.
