Topic: pbm can't mount usb disk with sme 7.6

[globalsi]

Hi,

I want to do a backup on a usb disk (ext3 - 1To). (I'll migrate this server to a new hardware with sme8)
When i plug the disk, I can't see it.

Here's my log :
dmesg

On other server (fedora6), the disk is seen correctly.
I run yum update, reboot but this change nothing.

Any idea about this ?
Thanks

please report all the issues in bugzilla, thank you

I would add that you could take a look at Affa (http://wiki.contribs.org/Affa) to migrate your server to the new HW

Thanks for your response,

Can i install sme8 with Affa on new server and run the migration from the old sme7.6 server ?
(I've got difficulties to install sme7.6 on the new server)

[Stefano]

first of all, file a bug for your issue and report here the reference for the future readers..

install SME8 on the new server, install affa on SME7.6 (the old one) and follow the howto.. I did it many times without any issue (I've got a SME6 migrated to SME7 on a new hw and then migrated to SME8 on new server again.. no problem)

Thanks for yours tips.

I'll file a bug next week (actually, i'm very pressed by this migration)

[CharlieBrady]

Do:

modprobe  sd_mod

and see if that makes a difference.

See https://bugzilla.redhat.com/show_bug.cgi?id=174537 for more detail.

On other server (fedora6), the disk is seen correctly.

Fedora6 has support for newer hardware which is not supported with RHEL4. Use an older tech USB disk enclosure if you can.

Hi,

Being on site yesterday, I just see that the disk is actually a raid-1.
After 10 min of use on my other server, it comes to crashes...
So I think the problem comes from my failed drive. With another usb drive, no worries.

thanks for your tips !
