Thanks for the suggestion, but mounting w/ the noatime option
doesn't<br>
affect the behavior.<br>
<br>
Anybody else have an idea?<br>

maybe changing relatime to noatime could help? <br>
see <a moz-do-not-send="true"

<strong><br>
2. noatime</strong> – This option stops recording the last file
access time when the file is just read. The <em>noatime</em>
option eliminates all the writes to the disk each time a file was
just read which previously used to happen with <em>atime</em>.
However a write is made to a disk in case if a file is being
changed/written.<br>

Hi folks.<br>
<br>
I have since switched to ext2 since my original message
below, yet I am<br>
still seeing the same behavior - / is being remounted every
5 minutes. I want<br>
to avoid this, to save wear & tear on the compact flash
card.<br>
<br>
Nothing in cron would be causing this...any ideas? I'm
running voyage 0.6.5,<br>
and the file system is mounted thus (ouput from mount
command):<br>
<br>
/dev/disk/by-label/ROOT_FS / ext2
ro,relatime,errors=continue 0 0<br>
<br>
Thanks.<br>
<br>

<span>My first guess is that writing to the journal on
EXT3 requires the FS<span> </span></span><br>
<span>to be writable. We use EXT2 on all of our flash
based media to<span> </span></span><br>
<span>minimize the number of writes.<span> </span></span><br>
<br>
<span>We once had a similar issue but it was an
incorrectly formatted cron<span> </span></span><br>
<span>entry. We have a custom script that remounts the
FS as writable, then<span> </span></span><br>
<span>does an aptitude update, package download, and
simulates an install,<span> </span></span><br>
<span>then emails the results. The error in crontab
caused this to be run<span> </span></span><br>
