Slackware :: Data Loss After Sudden Reboot On Xfs
Oct 25, 2010I have a laptop running slackware-current. The disk is /dev/sda and the root 'sda1' is xfs formatted (there is also linux swap at sda2).
recently I was trying to setup openvpn and had to copy a folder with configuration files from /usr/doc/openvpn_<version>/easy-rsa to /etc/openvpn.
I am sure the copying completed cause I got a prompt, but a few seconds later the battery died on me. When I got mains and powered it up, I could see the directory I copied under /etc/openvpn, and the files where all there too. but they all contained nothing. i.e. they had a size of 0.
I read [URL] Fthat an external journal filesystem for root is not supported. I am not sure If it applies to my situation though. As in does it use an internal journal instead?
and the bottom line is: shouldn't the copying have completed successfully? shouldn't I be worried, that this copy failed?

General :: [FYI] "last -f <old Wtmp> -x Reboot Shutdown" Incorrect For Last Reboot And Shutdown?
Mar 25, 2010Further to this LQ thread which Tinkster solved by suggesting the last command (thanks Tinkster) I have been exploring last -x reboot and have found that the reported duration is incorrect for the last reboot and shutdown when a old wtmp file is used. Not having a record for the following shutdown, last assumes that the system has been up until the current time and similarly for the shutdown.
The output comes in time order, latest first, each line showing the time of the reboot and the uptime from then to shutdown. Using last -x reboot shutdown to show the shutdown time, here's an illustration
Code:
shutdown system down 2.6.29.6-smp Sun Mar 7 15:35 - 03:02 (11:27)
reboot system boot 2.6.29.6-smp Sun Mar 7 09:35 (05:59)
09:35 until 15:35 is 05:59.
When the uptime exceeds 24 hours it is shown as (<days>+<hours:minutes) like this
Code:
shutdown system down 2.6.29.6-smp Sun Feb 21 12:39 - 13:20 (00:40)
reboot system boot 2.6.29.6-smp Sat Feb 20 09:39 (1+02:59)
09:39 until 12:39 the next day is 1 day 02:59.
The time in parentheses at the end of the shutdown lines is normally the time until the next shutdown.
So far so good. The incorrect output is for the last reboot and shutdown of an old wtmp file. Here's the output of last /var/log/wtmp -x reboot shutdown; last -f /var/log/wtmp.1 -x reboot shutdown
Code:
[snip]
reboot system boot 2.6.29.6-smp Fri Mar 12 07:42 (01:54)
shutdown system down 2.6.29.6-smp Fri Mar 12 01:31 - 09:37 (08:05)
wtmp begins Thu Mar 11 08:25:26 2010
[snip]
reboot system boot 2.6.29.6-smp Wed Mar 10 14:12 (15+01:42)
shutdown system down 2.6.29.6-smp Wed Mar 10 12:41 - 15:54 (15+03:13)
[snip]
The boot started at "Wed Mar 10 14:12" which had an actual uptime of 1 day 11:20 is reported as 15 days 03:13 which is the time from then until the last -f /var/log/wtmp.1 -x reboot shutdown command was issued. The time from shutdown to shutdown is similarly affected.

View 2 Replies View RelatedGeneral :: Possible UUIDs Changing Every Reboot?
Aug 1, 2011I have installed CrunchBang, then I moved the /tmp and /var to different partitions (I like to put these on reiserfs) the reason I did it after the install is because CrunchBang's installer doesn't give me the options to create reiserfs partitions during install (but does recognise reiserfs as I can manually mount them). Also these two partitions are logical.Anyway I have Windows 7 and Ubuntu 10.04 already installed and working fine but CrunchBang always changes the UUIDs of /var and /tmp when I reboot. Is that even possible I have also tried using the old method of /dev/sd** but of course that gets changed as well.

View 1 Replies View RelatedGeneral :: ASM Will Not Start Automoatically After A Reboot
Nov 3, 2010Running close to a go live date of 11/10/10 and need to have this fixed. DBA is pointing to the OS which is RedHat Enterprise Release 5.3. with Oracle RAC 10G
Oracle works fine it just won�t start up automatically after a reboot. After a reboot a person with root access has to increase the number of semaphores and then oracle will start and function. The next time the machine is bounced the same issue will arise and the semaphores need to be increased again by hand. Every time the machine is bounces the semaphores need to be increased by hand. This is not normal for a Unix machine. Semaphores are not part of the oracle install, it is a kernel parameter on Unix machines. Eventually after several reboots the semaphore parameter will be too high for the box to function. Once the semaphores have hit their peak, we reset them back to the original value and the whole process starts over again. This is a Unix build issue that has only surfaced on the production machines. The DAS development machines have the exact same oracle build and do not have this issue.
