[CentOS] CentOS 7.x Russian certification
Dear all, does anyone have any idea where to get a list of all CentOS 7.x versions that are certified to be used within Russia. My guess is that organizations, such as FSTEK, TR-CU declares those versions/distributions of CentOS that are certified to be used with commercial projects in Russia. Anyone with some information on this, plase advice, I would be very grateful. Regards, Gorazd ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Thanks for following up. ;) One more issue: while I can now switch between the two western keyboards and pinyin in the applications I use, as soon as I move between entry fields the keyboard selection resets to the default. Very annoying when you are using a second-choice western keyboard in an application and the keyboard selection constantly resets as you move between entry fields. The pinyin setting, on the other hand, remains as chosen which is the expected behavior. I use the default Ctrl-Space to activate/deactivate pinyin and right Ctrl-right Shift to move between the keyboard settings. Given the absence of a graphical configuration tool for fcitx in CentOS I am not sure where/how I can change the behavior for keyboard selection so that it does not change within any given application. Scott, do you know? Thank you. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Unrelated to the disk space issues, but the systemd-private-* directories are created by systemd services that have PrivateTmp turned on. THose services run with a private /tmp namespace, so they can't see the rest of the OS's /tmp. -- Jonathan Billings ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Could you please provide an example > of your usage? This morning. I sat down, opened my CentOS 7 laptop. It sprung back from suspension. I needed to check my project plan so I pressed the start key (some people call it Win key) and typed in "project plan". Tracker Search instantly listed all documents in my home that have "project plan" in either file name and content. I pressed down key twice and then enter to open the file that I wanted to edit. Five minutes later, I needed to edit a project specification. I pressed the start key and typed in "MyAwesomeProject specification". Tracker against listed all matching documents, and what I needed was usually among the top few choices. Another five minutes later, my insurer called and asked about some bill. I need a spreadsheet so I pressed start key and typed in "calc". LibreOffice Calc was the first choice so I directly pressed Enter to open it. I always use this method to open any app I need, and I won't have to touch the mouse. After this call, I need to schedule a meeting with a partner in London so I pressed the start key and typed in "london". Tracker showed the current time and I could press enter to see the weather in London. That's just what happened this morning. -- Yan Li ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Although I have to admit that the current GNOME Tracker extension is not perfect. Sometimes the search results don't show cities. Hope the GNOME 3.22 from RHEL 4.7 could fix this bug and bring more desktop functions. -- Yan Li ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

[CentOS] Power Fail Protection Update II
Many thanks once again to those that responded to my original posting (and my follow up message) with information about Network UPS Tools, other Linux-based tools like rtcwake, and commercial UPS products. We have quite a bit more evaluation and testing work to do before a power fail protection method is selected. I hope the discussion is as beneficial to others as it is to my organization. Along the way, one of our users pointed out that some of our CentOS 6 desktop/deskside machines actually throttle back power consumption in different ways than others. Instead of the yellow/amber LED display in the center of the power button, they flash green and then go solid green after the power button is pushed and the system wakes up. We have also noted that none of our CentOS 6 systems restart on their own when power is restored. This is the case whether power is lost during normal operation or when the systems are in a standby state when line power is lost. These two conditions or states (yellow/amber vs flashing green) have us wondering exactly what standby mode these systems are in and what settings may have been selected to send them to their standby state. Is there some sort of standard that applies to the standby states and are there BIOS settings or configuration files that control the what, how, and when standby is directed? Thanks to all and best regards. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] rsyslog stops logging on service reload?
The long and the short of the story was that another misconfigured client on the network was swamping the central logserver right after logrotate kicked offed. The best fix was to enable client memory/file queues.

Have you checked the power connections? Have you checked the power supply voltages durning spin up/later? Is there tension or major twisting forces on the sata cables? I've seen this cause intermittent problems and was solved by using a longer cable that reduced the stress at the connector. Are the drives getting hot (your' model shouldn't have a heat issue under normal conditions). Are the drives bolted into a system? Drives can be sensitive to vibration and identical, unmounted drives will tend to shake each other and can produce rotational torque as well (especially when the same model as they'll all have the same resonances in that case). Either can cause problems with keeping the heads over the track reliably. I'd definately run all the smart test. start with the conveyance test and then the short self test, and possibly the long test. do check the drive temperatures immediately after each test to make sure they aren't getting too hot. I assume you've done an fsck on the file systems? If not it might be good to check. Are you using the mother boards sata interfaces or an add-on card? If using a card i'd check the firmware version on the card and what the manufacturer is offering for updates. Are the drives still under warranty? If so try WD tech support. Also check that all the Raid tools are properly installed with their' dependencies met. could be other hardware/drivers interfering. might reset the bios to "optimized settings". Which software raid package are you using? Other than that I'd possibly suspect a software problem, not familiar with software raids myself (haven't used on, know what they are). Or possibly a problem with the drive that is intermitant or complex in how it fails. > > ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
