<DIV><FONT face=Arial size=2>Hi All,</FONT></DIV>
<DIV><FONT face=Arial size=2>I have one snapshot problem on ext3
filesystem.</FONT></DIV>
<DIV><FONT face=Arial size=2>I use RedHat 8.0, and I use lvm tools to create one
snapshot.</FONT></DIV>
<DIV><FONT face=Arial size=2>Then I use lvextend to extend the snapshot volume,
I can no longer mount it</FONT></DIV>
<DIV><FONT face=Arial size=2>My steps are as below:</FONT></DIV>
<DIV><FONT face=Arial size=2>1. First I create a volume group called test, and
create a volume called vol</FONT></DIV>
<DIV><FONT face=Arial size=2>2. I use lvcreate to create snapshot</FONT></DIV>
<DIV><FONT face=Arial size=2> lvcreate -s -l 50 -n snap1
/dev/test/vol</FONT></DIV>
<DIV><FONT face=Arial size=2>3. mount snapshot</FONT></DIV>
<DIV><FONT face=Arial size=2> mount /dev/test/snap1
/mnt/snap1</FONT></DIV>
<DIV><FONT face=Arial size=2>4. umount snapshot</FONT></DIV>
<DIV><FONT face=Arial size=2> umount
/dev/test/snap1</FONT></DIV>
<DIV><FONT face=Arial size=2>5. use lvextend to extend the snapshot
size</FONT></DIV>
<DIV><FONT face=Arial size=2> lvextend -l +10
/dev/test/snap1</FONT></DIV>
<DIV><FONT face=Arial size=2>6. mount snapshot again</FONT></DIV>
<DIV><FONT face=Arial size=2> mount /dev/test/snap1
/mnt/snap1</FONT></DIV>
<DIV><FONT face=Arial size=2>But error occur...the error message
is:</FONT></DIV>
<DIV><FONT face=Arial size=2>mount: block device /dev/test/snap1 is
write-protected, mounting read-only</FONT></DIV>
<DIV><FONT face=Arial size=2>mount: wrong fs type, bad option, bad superblock on
/dev/test/snap1,</FONT></DIV>
<DIV><FONT face=Arial
size=2> or too many
mounted file systems</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Regards,</FONT></DIV>
