When the system panics, it simply drops memory into the dump volume. (Traditionally, it used to use the swap partition.) Then, when the system is back up, you save that dump into regular files for subsequent analysis. If you're really tight for space, and aren't worried about debugging a panic, then disabling dumps entirely (dupadm -d none) might be appropriate in this case. (As an aside, I note that current OmniOS LTS - r151014 - doesn't understand dumpadm -e, which is a shame.) > Olaf > > > > Il 26 gennaio 2017 12:38:27 CET, v...@bb-c.de ha scritto: >> >> NAME USED AVAIL REFER MOUNTPOINT >>> rpool/dump 41.5G 9.15G 41.5G - >>> rpool/swap 4.13G 13.0G 276M - >>> >> >> The "dump" volume is much too big.

But dumps can also be saved as files on a normal dataset, right? provided enough space is left for them.

I recall an interesting post by Chris Siebenmann about dump/swap sizes (surprise) on OmniOS, here it is (the only one comment at time was mine :-) ): https://utcc.utoronto.ca/~cks/space/blog/solaris/OmniOSDiskSizing?showcomments#comments Cheers, Davide On Thu, Jan 26, 2017 at 12:22 PM, Fábio Rabelo wrote: > sorry, I forgot to change address to all list before send ... > > -- Forwarded message -- > From: Fábio Rabelo > Date: 2017-01-26 9:21 GMT-02:00 > Subject: Re: [OmniOS-discuss] Install on Supermicro DOM=low space left > To: "Volker A.
