Scott & Jeff,<br><br>Thanks for the tool ideas. I've tinkered with GFS before. The servers are RHEL 5 so that's a (relatively) easy route.<br><br>new issue is fiber cards are 4x PCIe in an 8x slot. bandwidth is 1/2 the rated capacity of 4Gbps. Grr. chunking around TB is a chore.<br>

Oracle’s web site. It’s designed to allow you to use the same storage in
a clustered configuration. We use its predecessor OCFS for one of our old
Oracle RAC environments but RAC isn’t required as OCFS2 handles its own
clustering setup. Its also reportedly a much improved product over
OCFS(1). It uses Linux’ O_DIRECT stuff for the file sharing so the
tools you use have to be O_DIRECT aware and I think most of the newer ones
(tar, ls, cp, mv etc…) are. When we did it back on RHEL3 (2.4
kernel) we had to load the utilities Oracle had made that were (also open source).</span></font></p>

<p class="MsoNormal"><font face="Arial" size="2" color="navy"><span style="font-size: 10pt; font-family: Arial; color: navy;">Also GFS I believe is designed for similar
usage and is native to most distros but I haven’t used it.</span></font></p>

<p class="MsoNormal" style="margin-bottom: 12pt;"><font face="Times New Roman" size="3"><span style="font-size: 12pt;">I have a netapp joined by
fiber channel to 2 linux head end servers. I'm using multipath fiber channel in
an active/active mode for maximum data throughput.<br>
<br>
box
1 can write a file and read that file is there. Box
2 can't see the file exists. <br>
box
2 can write file and see it on the netapp but box
one does not see it.<br>
<br>
run sync on both boxes and umount/mount the netapp storage space again.<br>
both box
1 & 2 see the file written from box
1 but the file written from box
2 is gone.<br>
<br>
this is bad. Clearly I have a misconfiguration somewhere! Box
2 shows errors related to ext3 journal corruption
so ext3 is NOT a good choice.<br>
<br>
Box
2 is supposed to be a failover database and the
netapp is the storage for the database files. I would prefer for the failover
to be closer to a hot standby than a cold standby but it looks like I can't
keep the netapp partition mounted on box
2 if box
1 is still live. I'm not running the database at
all on box
2.<br clear="all">
