Is it a stupidity or something else?
From time to time I receive job offers and do job market research to keep abreast and be well informed regarding the current state of IT sphere and what opportunities exist out there. As a result I have to sift through all kind of job offers and job descriptions which match “unix solaris san networking” […]
Are we going to say goodbye to Sun branded USP V/VM?
Just received it today: 2 March 2010 Dear Valued Partner, Due to the recent acquisition of Sun Microsystems by Oracle Corporation, there has been much speculation as to the effect the merger will have on the market, product offerings and partnerships. As you are aware, Hitachi Data Systems and Sun Microsystems have enjoyed a successful […]
Expanding Solaris filesystem
Of course, you know about growfs command which is a key tool if you’re aiming at expanding a UFS file system in non-destructive way. But sometimes you may see the following error message as a result of growfs attempt: failed to disable logging The reason why this error happens is not obvious though. From the […]
Footsteps of spring
Hooray, finally it could be distinctly heard marching down a corduroy and once you’re left with the last sheet of a tear-off calendar in you palm you could crumple it and let the spring in. In the end, you don’t have a choice since tomorrow is the first day of her reign. So you’d better […]
VxVM is watching after you
Couple of days ago my colleague told me about one neat feature of VxVM 5.x that could be quite helpful in the field. Imagine a situation when a customer complains about VxVM misconfiguration and blames your team for a slime work. To prove him wrong, you could sift through VxVMs’ command log files to get […]

It’s worth noting that prior to OS upgrade I’d successfully updated OBP to the latest release – 5.20.14. SunOS Release 5.10 Version Generic_141444-09 64-bit Copyright 1983-2009 Sun Microsystems, Inc.

An obvious decision was to check the disk with format utility. […]
Send a complete zfs pool
Imagine, that you have a zfs pool with dozens of zfs datasets which you need to migrate to another box. “How do I accomplish that” is a reasonable question. Actually, that’s dead easy with zfs send/receive mechanism: # zpool list zones NAME SIZE USED AVAIL CAP HEALTH ALTROOT zones 67.5G 30.5G 37.0G 45% ONLINE – […]
Scanty vocabulary
I do believe that nowadays English language is hugely simplified in day-to-day use. Just listen to this:
Jumping from FC10 to FC11
Finally I had enough spare time to sit down and carefully upgrade my VPS to Fedora Core 11 using the recommendations to steer clear of any possible issues. Needless to say everything went without a hitch. The only thing that should be redone is clamav which I setup in hast but that’s trivial.
