Hello, When I run lvcreate and lvremove I get the errors you can see at the bottom of this email. I have been seeing this on kernels I configured from scratch, right now this is version 3.5 on an x64 running ArchLinux. I must have made a mistake with the kernel's options or I am overlooking something. It's clearly a configuration option because I don't get these errors with ArchLinux's distribution kernel. So what am I doing wrong? Note, LVM does work fine apart from these issues. After many compiling iterations I'm all out of ideas and while I'm aware that one can work around the errors LV's with the -Zn options, I'd rather get this stuff fixed :) This is my kernel config: http://pastebin.com/isVsziSe The error: # lvcreate -L100M -n foobar -v array /dev/array/foobar: not found: device not cleared Aborting. Failed to wipe start of new LV. semid 983040: semop failed for cookie 0xd4d19ee: incorrect semaphore state Failed to set a proper state for notification semaphore identified by cookie value 223156718 (0xd4d19ee) to initialize waiting for incoming notifications. I appreciate all help I can get. -- Kind regards, Mark van Dijk. ,----------------------------------- -------------------------------' Tue Aug 07 12:00 UTC 2012 Today is Prickle-Prickle, the 73rd day of Confusion in the YOLD 3178 _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
