<font size=2 face="sans-serif">Hi Renar, </font><br><br><font size=2 face="sans-serif">whenever an access to a NSD happens,
there is a potential that the node cannot access the disk, so if the (only)
NSD server is down, there will be no chance to access the disk, and the
disk will be set down.<br>If you have twintailed disks, the 'second' (or possibly some more) NSD
server will be asked, switching to networked access, and in that case only
if that also fails, the disk will be set to down as well. </font><br><br><font size=2 face="sans-serif">Not sure how your setup is, but if you
reboot 2 NSD servers, and some client possibly did IO to a file served
by just these 2, then the 'down' state would be explainable. </font><br><br><font size=2 face="sans-serif">Rebooting of an NSD server should never
set a disk to down, except, he was the only one serving that NSD.</font><br><br><font size=1 face="Arial"><br>Mit freundlichen Grüßen / Kind regards</font><p><font size=2 face="Arial"><b>Achim Rehor</b></font><p><table width=600 style="border-collapse:collapse;"><tr height=8><td width=600 colspan=4 style="border-style:none none none none;border-color:#000000;border-width:0px 0px 0px 0px;padding:0px 0px;"><div align=center><hr noshade></div><tr height=8><td width=600 colspan=4 style="border-style:none none none none;border-color:#000000;border-width:0px 0px 0px 0px;padding:0px 0px;"><font size=1 face="Arial"> </font><tr height=8><td width=496 colspan=3 style="border-style:none none none none;border-color:#000000;border-width:0px 0px 0px 0px;padding:0px 0px;"><font size=1 face="Arial">Software
