Hi, Since nfs-utils 1.2.1, there are some problems with crossmnt usage. See Debian bug http://bugs.debian.org/567546, but in short the problem seems to be that sub-mounts (/a/b) take the top-level mount (/a) options instead of their own, due to a bug in how mountd generates the crossmnt subexports. I checked that reverting the write_secinfo changes in commit bc0a6ab03089fc1ea4fea26ed9635c2cc918b01b fix the issue, but that might only be a side effect, not the actual cause. A short test: - have /a and /a/b exported, with different flags (e.g. ro on /a, rw on /a/b) - restart the mountd, clear exports, etc. - try a mount on the client of /a/b, it gets readonly - umount & remount, it's now r/w - however, clearing the kernel export table (exportfs -f), makes the next mount again get read-only Disabling crossmnt fixes the issue completely, so I would venture to guess that the subexports creation code has some issue, but I don't know enough of this to be able to debug it. thanks, iustin -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
