I've set up everything and have moved close to 2Tb of data to the glusterFS volume without incident. I thought that I try a recursive long listing just to make sure everything was working properly (in anticipation of doing just that when I turn on AFR soon). Doing ls -alR on mounted GlusterFS volume. Everything looks good, but every so often I get output that looks like: -rw------- 1 zope zope 30512 Jan 27 2008 efb1f22f2312af6ed5fbef014ee3 ?--------- ? ? ? ? ? /mnt/BACKUPS/blobdata/00/66/1ac485 0e731fed2e0eb2fdbc8d05 ?--------- ? ? ? ? ? /mnt/BACKUPS/blobdata/00/66/1d7d22 6f5f6845d62fddcadb4ca9 ?--------- ? ? ? ? ? /mnt/BACKUPS/blobdata/00/66/284371 d43c24d0d3267109c674e7 If I stop the listing and check the files individually I get: [zope at zodb01 prodscripts]$ ls -al /mnt/BACKUPS/blobdata/00/66/1ac4850e731fed2e0 eb2fdbc8d05 -rw------- 1 zope zope 23328 Aug 12 2008 /mnt/BACKUPS/blobdata/00/66/1ac4850e73 1fed2e0eb2fdbc8d05 [zope at zodb01 prodscripts]$ ls -al /mnt/BACKUPS/blobdata/00/66/1d7d226f5f6845d62 fddcadb4ca9 -rw-rw-r-- 1 zope zope 1616 Nov 2 2007 /mnt/BACKUPS/blobdata/00/66/1d7d226f5f6 845d62fddcadb4ca9 [zope at zodb01 prodscripts]$ ls -al /mnt/BACKUPS/blobdata/00/66/284371d43c24d0d32 67109c674e7 -rw-rw-r-- 1 zope zope 34928 Dec 28 2007 /mnt/BACKUPS/blobdata/00/66/284371d43c 24d0d3267109c674e7 [zope at zodb01 prodscripts]$ Nothing appears to be wrong.

Sometimes it affects entire folders not just individual files: ls: /mnt/BACKUPS/blobdata/00/e1: Permission denied Stopping the recursive listing and just executing on this single folder works perfectly.
