If by any mean I send to de device anything else than the predefined strings, stated by the manufacturer, the device ceases to respond. The only way I found its to turn off and then turn on the thing again. Which its very impractical. Its there any way to "reset de UART chip on the device" or send some string based on the RS232 standard that clean the device buffer?... Hi all! I want to allow only 1 device to bond at a time. If another device bonding, I want to delete the previously bonded one. I tried to use dm_device_delete_all() in DM_EVT_SECURITY_SETUP_COMPLETE event, but it delete the current device too.
If you do an "ls -l" on /dev/mapper/* it will tell you that those are symbolic links to the /dev/dm-* files. Files in /dev/mapper are named according to the volume groups …... Using partx it would also be possible to delete any partitions that are not needed behind the root volume, expand the root volume, delete the kernel view on that partition (partx -d -n X /dev/sda), update the root partition (partx -u -n X /dev/sda) and then resize the filesystem.
On my destination server, the iostat command shows a device at the bottom, /dev/dm-0, as being 100% utilized. This server has 6 disks in a mdadm raid5 set, with LVM running on top of it. Each of the underlying disks are sitting around 50% util. The transfer is … how to connect air to ipone Remove any reference to the device's path-based name, like /dev/sd or /dev/disk/by-path or the major:minor number, in applications, scripts, or utilities on the system. This is important in ensuring that different devices added in the future will not be mistaken for the current device.
Duplicate /dev/dm- devices for multipathed SAN LUN.
My > question is how can I initialize the drives without booting to rescue mode ? > And how can I get rid of the /dev/dm-0 device ? > > dmraid still shows the 2 devices.
Ditto, running an ext4 /boot partition with LVM of /dev/sda2 and a 28 GB partition for /usr at the back of it all. All possible partitions encrypted.
