How use thin snapshots with a non-thin root filesystem ?
by Sreyan Chakravarty 21 Nov '20

21 Nov '20

I am looking into thin snapshots since the older COW snapshots delay my boot enormously. My normal root fs is on a normal "non-thin" volume. So to make a snapshot I have boot into a live cd environment then set my root fs volume to read-only and then set it to inactive. Commands: sudo lvchange -pr vgfedora/fedora sudo lvchange -an vgfedora/fedora Now I create the thin snapshot using lvcreate, after that I need to restore my root LVS to its original state: sudo lvchange -ay vgfedora/fedora sudo lvchange -prw vgfedora/fedora This fails with: Command on LV vgfedora/fedora uses options that are invalid with LV parameters: lv_is_external_origin. I mean what is the point of creating a thin snapshot if I can't change my original volume ? What am I doing wrong? -- Regards, Sreyan Chakravarty

Let me know if I am doing anything wrong. I am checking the boot logs via : journalctl -b Also no change in the dmesg output. Nevertheless, the think I have found the problem: Nov 20 21:14:15 dracut-initqueue[902]: Scanning devices dm-0 for LVM logical volumes vgfedora/fedora Nov 20 21:14:16 dracut-initqueue[927]: inactive Original '/dev/vgfedora/fedora' [700.00 GiB] inherit Nov 20 21:14:16 dracut-initqueue[927]: inactive Snapshot '/dev/vgfedora/pre_kde_Nov_9' [70.00 GiB] inherit Nov 20 21:17:27 systemd[1]: Found device /dev/mapper/vgfedora-fedora.

As you can see there is a 3 minute delay to load or find the snapshot. The question is what do I do now ?

It depends ... - When you want to burn a Audio-CD to be played by an (old-style) CD-Player the files must be in WAV format, sampling rate must be 44.100 Hz and stereo. - Newer CD-Players support the MP3-format also for the tracks and you must convert convert WAV to MP3 by your own. Afterwards you burn an ISO 9660 file system. Conversion can be done by lame, burning by growisofs. HTH, Frank -- Regards, Sreyan Chakravarty

Perhaps I overlooked, but I miss one line. About “query” I have also: allow-query { 0.0.0.0/0; ::1/128; 2001:470::/32; }; Perhaps allow-query { any; }; would be sufficient...

I've done the following tests on my name server: I've inserted some acls into the named.conf file, the middle two are the hostnames and IPs of some PCs on the LAN, the last is the original "everyone on my LAN" declaration: acl "itself" { 127.0.0.1; }; acl "rocky" { 192.168.1.1; }; acl "fluffy" { 192.168.1.12; }; acl lan { 192.168/16; 127.0.0.1; }; And inserted some views into the named.conf file before all the other zone files: view itself { match-clients { itself; }; zone "viewtest" { type master; file "viewtest.itself.zone"; }; }; view rocky { match-clients { rocky; }; zone "viewtest" { type master; file "viewtest.rocky.zone"; }; }; view fluffy { match-clients { fluffy; }; zone "viewtest" { type master; file "viewtest.fluffy.zone"; }; }; view lan { match-clients { any; }; zone "viewtest" { type master; file "viewtest.lan.zone"; }; // the rest of my original zone files are here }; With the last entry being a fall-back with my pre-existing zone records. And created those zone files thus: viewtest.itself.zone file: $ORIGIN . $TTL 86400 ; 1 day viewtest IN SOA viewtest. hostmaster.viewtest ( 42 ; serial 300 ; refresh (5 minutes) 900 ; retry (15 minutes) 3600 ; expire (1 hour) 1800 ; minimum (30 minutes) ) NS ns.viewtest. A 192.168.1.1 MX 1 mail.viewtest. $ORIGIN viewtest. ns A 192.168.1.1 www A 127.0.0.1 viewtest.rocky.zone file: $ORIGIN . $TTL 86400 ; 1 day viewtest IN SOA viewtest. hostmaster.viewtest ( 42 ; serial 300 ; refresh (5 minutes) 900 ; retry (15 minutes) 3600 ; expire (1 hour) 1800 ; minimum (30 minutes) ) NS ns.viewtest. A 192.168.1.1 MX 1 mail.viewtest. $ORIGIN viewtest. ns A 192.168.1.1 www A 192.168.1.1 the viewtest.fluffy.zone file: $ORIGIN . $TTL 86400 ; 1 day viewtest IN SOA viewtest. hostmaster.viewtest ( 42 ; serial 300 ; refresh (5 minutes) 900 ; retry (15 minutes) 3600 ; expire (1 hour) 1800 ; minimum (30 minutes) ) NS ns.viewtest. A 192.168.1.1 MX 1 mail.viewtest. $ORIGIN viewtest. ns A 192.168.1.1 www A 192.168.1.12 the viewtest.lan.zone file: $ORIGIN . $TTL 86400 ; 1 day viewtest IN SOA viewtest. hostmaster.viewtest ( 42 ; serial 300 ; refresh (5 minutes) 900 ; retry (15 minutes) 3600 ; expire (1 hour) 1800 ; minimum (30 minutes) ) NS ns.viewtest. A 192.168.1.1 MX 1 mail.viewtest. $ORIGIN viewtest. ns A 192.168.1.1 www A 192.168.1.112 In those zone files, I've set the www record to different IPs for each record, but left everything else the same. When I do a "dig www.viewtest<http://www.viewtest>" command on the rocky PC (so called for being a wobbly case), I get the expected result of 127.0.0.1. The nameserver is running on that machine, and the command line comes from localhost rather than its network address. When I do a "dig www.viewtest<http://www.viewtest> @192.168.1.1" command on the rocky PC, I get the expected result of 192.168.1.1. This time I've told dig to query a specific address, and it's bypassing localhost. When I do a "dig www.viewtest<http://www.viewtest>" command on the fluffy PC (so called for the box being full of fluff when I acquired it - yes I like obvious names), I get the expected result of 192.168.1.12. When I do a "dig www.viewtest<http://www.viewtest>" command on another PC that doesn't have a specific ACL, I get the expected fallback 192.168.1.112 address. So, ACL and VIEW declarations work as expected here (specific matches get their special answers, everyone else gets the fallback). I'll admit that the server is running CentOS 7, and the client is Fedora 32, but the installation of BIND is bind-9.11.4-26.P2.el7_9.2.x86_64, and I'd expect Fedora's to work the same. Things to watch out for: Overlaps of identities: In my case, I did the test on the nameserver PC (rocky) and two separate ones. The server PC has two IPs that could be used in its communications (127.0.0.1 and 192.168.1.1), the localhost address was what it used as that's how the machines work by default (localtraffic on the localhost). Typing errors: The names used in ACLs must exactly match the names inside the MATCH-CLIENTS used inside the VIEWs. I've also used the same name for the VIEW, and inside the zone filename, just for my own convenience of not making mistakes. Check you've written match-clients and not match-client. Check you've got braces and semi-colons in the right places. Check you've written the correct filenames inside the zone declarations. Check you've typed IP addresses correctly. When testing your external IP, how are you testing it? Are you actually doing a query from an outside machine? Are you using the IP you think you are? -- uname -rsvp Linux 3.10.0-1160.6.1.el7.x86_64 #1 SMP Tue Nov 17 13:59:11 UTC 2020 x86_64 Boilerplate: All unexpected mail to my mailbox is automatically deleted.

Growisofs is for burning ISO9660 file systems. Wodim is mainly for burning CDDA formatted CDs. > Can growisofs be used for reading as well as writing to a disc? No. It is for writing only. I guess you should the man pages of wodim and growisofs as it will answer most if not all questions. --Frank -- Regards, Sreyan Chakravarty
