Junos OS

Experts,

I believe I deal with corrupted partition on 2200 C while trying to upgrade to 15.1R5 always have this:

ERROR: /dev/da0s1a is not JUNOS snapshot

I tried to fallow many links and no luck - should I create RMA for that switch?

also it shows the isntaller exited with status 2

installation was unsucesfull

anybody?

I guess I will be opening tach case

Looks like you don't have enough space on the file system.

Try running storage clean up first.

request system storage cleanup

If this doesn't give enough stpace automatically, try removing the image file and mounting it from a USB drive to install from there instead.

Thank You - that did the trick

Solved the same Problem with:

request system snapshot media internal (solves error message no juniper partition)

request system storage cleanup

(scp image file to /var/tmp)

request system software add /var/tmp/image-file nocopy no validate

Juniper told me not to install 15.1 on any EX2200. They do not have enough RAM to support it.

well - they keep saying different story - all think it depends how knowledgeable is Juniper Tech working on the specific case. Last time they told me to install only JUNOS 15.1R6.7 as fixes ram issue, earlier version has ram issue.  

Now I am confused, and thinking opening tech case again. 

Going through the release notes looking for known behaviors or issues on the ex2200 I don't see anything listed about the memory issue.  And I would hope that any posted version for download is one that would run on the platform.

But my sense is a JTAC case is probably best then to confirm all this.

See these TSB's:

At some point 15.1 was declared recommended for all legacy switching platforms. After continued memory issues across all models Juniper reversed and now recommends 12.3 (see recommended release page). 15.1 is banned on all 2200/4200/8200 equipment here after multiple major outages.

Nice catch on the TBS, I'm surprised they are not linked on the download page for the ex2200 junos.  But now that you mention it here, I see they are included on the JTAC recommended release kb with a note recommending against usings 15.1 on the ex2200.

ok so should I start planning  reverting all firmware to Junos 12.3R12-S7 ? since the vacation time is coming I can do that easily in a month from today, I would revert the firmware on 2200C and 3300 since they all have 15.x - I am glad I left 4300 on 14.x - stable at that time 

P.S I have dig in how to revert firmware to 12.3 on 2200C and 3300 ......

There are special case instructions noted for downgrade from 15.1 to 12.3 in the TBS above too. 

DOWNGRADE NOTICE - PLEASE REVIEW KB31903 BEFORE ATTEMPTING A DOWNGRADE FROM 15.1 to 12.3R12:

Please review this KB31903 before attempting a downgrade to 12.3R12 from the JUNOS 15.1 releases. There is a change in behavior in the way password hashing between these releases, which this KB31903 describes in detail, and ensures that passwords are stored in the same form between JUNOS 15.1 and 12.3R12 software releases.

Thank you Steve - you are the best !!!! I will be back in a month when doing the Juniper project. Thanks
