ufw allow samba Please

I've been obsessed with sharing my desktop files over the home network to all the devices connected to my home router. I finally did it once as I said here. Since then, after several reinstalls and wipes of hard drives, I lost the configuration file for the original system. In short I can't make it work. I've forgotten how I did it exactly.
It turns out that samba and my samba configuration files aren't to blame.

I was doing firewall configuration files with my rkhunter setup. I noticed that I don't have any entry for samba. I added my samba rule in the firewall. I checked my smartphone file manager and there it is my shares automatically appearing and ready for use. No login required.

The firewall rule is:
#ufw allow samba

RAID Resync Interrupted - How To Recover

Using Ubuntu 16.04 with RAID and Logical Volumes. I am adding Disk Encryption to my skill set. After using the Fedora 24 installer to do all of these in one night (and day) of operating system installation fiesta, I am now trying to finish the same thing using the Ubuntu installer this early morning. There's a power loss of about 30 seconds. It happens in the very early morning. Some power engineer decided to test a new hardware or to pull out an equipment for servicing in the wee hours of the morning while I'm in the middle of resyncing my RAID. I heard the sigh of the fan motors.

I checked the status of the RAID - inactive, okay. Then bring it back on, right? I had to continue the resync somehow so I went back to the mdadm man pages.

#mdadm -assemble --update=resync /dev/md0 /dev/sdb1... /dev/sdd1

 This returns a message that my component devices are BUSY. Are they just trying to ignore me? Not at this ungodly hour, okay. So I have to stop the devices.

#mdadm /dev/md0 --stop

I retried the previous command. It worked. The resync restarted from where it was interrupted.

Good night. Oh it's morning. Good morning then.

Restoring LVM Post-Install

I had to reinstall my linux operating system with an existing LVM over RAID. During the install I formatted one of the physical volumes PV. I used it for / (root), swap and /boot partitions. I could have used the existing Logical Volume LV for these but this device is also encrypted. I doubt I can reuse it without unlocking it. So I simply wiped it clean and made a clean install. After reboot I checked the status of the LVM and the RAID. Both are okay-ish. The RAID is clean according to mdadm. LVM informed me that the volume group is degraded. I'm missing a physical volume. I know I wiped it clean.

So how do I restore the volume group so I can get at my data.

LVM keeps its configuration files in /etc/lvm/backups and also in /etc/lvm/archives/"name-of-volume-group". So pick the current or latest one in /etc/lvm/backups or the older ones in /etc/lvm/archives/"volume-group". You need two things - the backup configuration file and the UUID of the physical volume. Using the terminal type:

#pvcreate --uuid UUID  --restorefile PATH-TO-THE-BACKUP-FILE-VOLUME-GROUP.VG /dev/sda

Unfortunately, I get an error message telling me that the Device is not found. (or ignored by filter). So I have to check the /etc/lvm.conf if by chance my device is simply being ignored or left out, simply not detected due to an uncommented line in the file.

I think in my case the physical volume was really wiped out, formatted, erased including the metadata. So, can I restore the volume group instead with the remaining physical volume? With the commands pvdisplay, vgdisplay and lvdisplay, it looks promising that I could. After consulting the man pages for vgreduce and vgchange I hit the terminal again.

#vgreduce --removemissing  ubuntu-vg

If you have data in the missing volumes, first try to salvage it. Afterwards, the remaining logical volumes are activated with this command:

#vgchange --activate y ubuntu-vg

Now check the status of your LVM with pvdisplay, vgdisplay and lvdisplay. My logical volumes now appear on the file manager, so that's a good sign I have saved the data.

Status of Logical Volumes After 30 Days

It's been a while since I created these logical volumes and extended my volume group (the only one) to include the newly grown raid5 array on a 2-2-1 TB device. Frown all you want as long as it works. When that 1 TB HDD shows some signs of failing or error, I'll replace it with a 2TB HDD. The raid array will then be a complete 2-2-2 TB raid5.

Here's the status of the raid array now:


I'm replacing the 1 TB HDD when it fails or errors, or when I need to increase the capacity of the array, whichever comes first. The present raid array size is 2 TB.
