<div dir="ltr">On a stock RHEL 5.1 server, an ext3 fs image (i1) is mounted as loopback at /mnt/m1. /mnt/m1 is exported as NFS share to be used by a RHEL 5.1 client.<br><br>Not sure since when, on the NFS server, <br><ul><li>
one can not see m1 when ls /mnt anymore. Meanwhile,</li><li>'cd /mnt/m1' and 'ls /mnt/m1' and file creation under /mnt/m1 all work just fine under /mnt/m1.</li><li>mkdir /mnt/m1 fails saying '/mnt/m1 is present'</li>
<li>/proc/mounts still have /mnt/m1 listed as mounted loopback.<br></li><li>umounting /mnt/m1 & mounting it back works just fine. still cannot see 'm1' under /mnt.<br></li><li>/mnt/m1 is under constant use by the NFS clients, so 'rm -rf' or 'umount' of /mnt/m1 from the server actually fails.<br>
