Yep, says /dev/xxx. Seems -u is maybe only used in recovery or other restoration operations. Thank you.

Recommended way to pvcreate please and if you can give me the URL to the documentation? pvcreate /dev/sd? Or pvcreate -u once blockid or other commands give the uuid? Thank you.

I own it. I am experimenting and this happened yesterday before I got as far as pvcreate and I was just wondering if everything would be ok with LVM and fstab etc if the /dev/sd? changed. I have read the LVM puts its own UUIDs on the disk/partitions and searches for these after a reboot to...

Hi, In hyper v today, I created a 4TB vdisk as 2nd disk / powered up OL7.9VM, saw it as /dev/sdb in lsblk / powered down vm / deleted the 4TB vdisk and saved settings. I then recreated it in hyperv settings as the 2nd disk again. Powered up VM Now this 4TB disk is /dev/sda and the OS disk is...

Does it matter what the command or redirection of stdin is for the command? Its the fact that sudo thinks the first redirection for the command is the redirection for the sudo password. You could do this if /bin/cat was in sudoers for the user: ssh -t myname@server2 "sudo -S /bin/cat...

Hi, Please help, sudo thinks the password file is v-users. ssh -t -l myname server2 "cd /etc/mail; sudo -S /usr/sbin/hashmap v-users < v-users < ~/mypw.txt" Ssh keys already set up for mynane. Cat'ing the pw.txt and then pipe the sudo doesn't work either I have tried all sorts of quoting but I...
