I did this step successfully: root@b2:~# pvdisplay --- Physical volume --- PV Name /dev/sda2 VG Name bubba PV Size 455.43 GiB / not usable 3.65 MiB Allocatable yes PE Size 4.00 MiB Total PE 116588 Free PE 111442 Allocated PE 5146 PV UUID SMvR2K-6Z3c-xCgd-jSR2-kb1A-15a2-3RiS6V root@b2:~# lvdisplay --- Logical volume --- LV Path /dev/bubba/storage LV Name storage VG Name bubba LV UUID 91yHxQ-RmOW-OeDv-jaIv-1z1B-KBSk-yCsDC6 LV Write Access read/write LV Creation host, time , LV Status available # open 1 LV Size 20.10 GiB Current LE 5146 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 253:0 > Create a new LV of adequate size.

Reducing > is risky, as you experienced. I want to create one LV for /usr and one LV for /var. But I can't create a LV with: # lvcreate --size 10.10G -n usr bubba Rounding up size to full physical extent 10.10 GiB /dev/bubba/usr: not found: device not cleared Aborting. Failed to wipe start of new LV. semid 1114120: semop failed for cookie 0xd4d6ff6: incorrect semaphore state Failed to set a proper state for notification semaphore identified by cookie value 223178742 (0xd4d6ff6) to initialize waiting for incoming notifications. I don't understand why can't create a new LV with this command abowe? And don't understand why is successful following command? # lvcreate -vvv --size 10.10G -n usr bubba I search on Internet and found another solution: # lvcreate -Zn --size 10.10G -n usr bubba Rounding up size to full physical extent 10.10 GiB WARNING: "bubba/usr" not zeroed Logical volume "usr" created semid 1146888: semop failed for cookie 0xd4d9b50: incorrect semaphore state Failed to set a proper state for notification semaphore identified by cookie value 223189840 (0xd4d9b50) to initialize waiting for incoming notifications. Can I use now this newly created LV to make on it an ext4 filesystem despite the fact that it is not zeroed? -- Regards from Pal -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
