/dev/urandom issue that was fixed in suse kernel version 3.0.74

We ran into this issue and are rolling out the fix provided by Novell. Novell was telling us that it was due to a large number of ssh logins to a host but this does not always seem to be the case. Anyone have a more definitive reason for what caused the error and how it was fixed? Chris Will

Re: Amount of memory in buffers shown by the free command

Alex and Rob, Thanks for the replies. It looks like the buffers value shown by free on SLES is the the sum of the Cached and SReclaimable values from /proc/meminfo/, while on RHEL it is just Cached. On SLES: # egrep '^Cached|^SRe' /proc/meminfo;free Cached: 130336 kB SReclaimable:

You should take a look on your initrd too. Maybe the lv_swap is still referenced there. Try recreating it to see if the ghost lv vanishes for good. Mauro http://mauro.limeiratem.com - registered Linux User: 294521 Scripture is both history, and a love letter from God. 2013/5/16 Steffen Maier

2013-05-16 Thread Neale Ferguson
That was it Steffen. I did a find / grep looking for vg_swap so I thought it'd pick up the zipl.conf but I must have messed up the command. In any event, I got rid of it and re-ran zipl. Note, that rd_LVM wasn't put in manually by me but as part of the installation. Many thanks... Neale On

Mike Rob, That is not what I see at my end. Below are sample of RHEL 5.9 and RHEL 6.3. In both cases, the number of cached from the 'free' command matches to the number of cached found in /proc/meminfo. Strange but true.. $ cat /etc/*se Red Hat Enterprise Linux Server release 6.3 (Santiago) $
