[opensuse] rsync question--link-dest= question

07 Aug '19

Hi, Suppose I do this rsync run: OPTIONS="--archive --acls --xattrs --hard-links --sparse --stats --human-readable " DESTINATION=001 rsync $OPTIONS --password-file /root/cripta/keys/rsync.secrets \ --relative --include=/data/vmware** --include=/data/storage_** --include=/data/cripta** --include=/data/xtr** --include=/data/raid** \ --exclude=/lost+found --exclude=/dev --exclude=/sys --exclude=/proc --exclude=/run \ --exclude=/data/** --exclude=/mnt --exclude=/other --exclude=/media --exclude=/var/lib/samba/lock/ --exclude=/var/run/ \ / root@Isengard::MyBook_Telcontar/$DESTINATION This creates a backup run to machine Isengard wich has an rsyncd daemon running. We can check on it this way: Telcontar:~ # rsync --password-file /root/cripta/keys/rsync.secrets root@Isengard:: mirrors clonar directorio a disco externo de archivado fusion clonar directorio a disco externo de archivado Videos clonar directorio a disco externo de archivado MyBook_Telcontar copia de seguridad de Telcontar Telcontar:~ # We can see the directories there: Telcontar:~ # rsync --password-file /root/cripta/keys/rsync.secrets root@Isengard::MyBook_Telcontar drwxr-xr-x 28 2019/08/05 16:09:19 . drwxr-xr-x 0 2019/08/01 14:55:28 000 drwxr-xr-x 384 2018/11/24 11:04:40 001 drwxr-xr-x 364 2018/11/24 11:04:40 002 drwxr-xr-x 22 2019/08/05 16:14:45 cosas Telcontar:~ # The backup is created. Now, when I do a second backup, the intention is to do it to another directory (002), making all unchanged files hard links to the previous backup. rsync is informed of the existence of a previous backup using "--link-dest". I have done this before on local directories: rsync $OPTIONS --link-dest=$PREVIOUS/boot /boot /$DESTINATION Now, this does not work: OPTIONS="--archive --acls --xattrs --hard-links --sparse --stats --human-readable " DESTINATION=002 PREVIOUS=001 rsync $OPTIONS --password-file /root/cripta/keys/rsync.secrets --link-dest=root@Isengard::MyBook_Telcontar/$PREVIOUS/ \ --relative --include=/data/vmware** --include=/data/storage_** --include=/data/cripta** --include=/data/xtr** --include=/data/raid** \ --exclude=/lost+found --exclude=/dev --exclude=/sys --exclude=/proc --exclude=/run \ --exclude=/data/** --exclude=/mnt --exclude=/other --exclude=/media --exclude=/var/lib/samba/lock/ --exclude=/var/run/ \ / root@Isengard::MyBook_Telcontar/$DESTINATION I get this error: --link-dest arg does not exist: root@Isengard::MyBook_Telcontar/001 But it does, AFAIK: Telcontar:~ # rsync --password-file /root/cripta/keys/rsync.secrets root@Isengard::MyBook_Telcontar/001 drwxr-xr-x 384 2018/11/24 11:04:40 001 Telcontar:~ # Telcontar:~ # rsync --password-file /root/cripta/keys/rsync.secrets root@Isengard::MyBook_Telcontar/001/ drwxr-xr-x 384 2018/11/24 11:04:40 . -rw-r--r-- 52,184 2016/12/24 00:59:15 .readahead -rw------- 19,127 2017/09/25 02:03:08 DEADJOE -rw------- 4,288,512 2015/02/24 14:28:22 core drwxr-xr-x 24 2016/03/14 14:40:16 %{_rundir} ... I also tried: rsync $OPTIONS --password-file /root/cripta/keys/rsync.secrets --link-dest=$PREVIO \ ... --link-dest arg does not exist: 001 What am I doing wrong? Or is --link-dest not supported on rsyncd daemon (remote)? Both $DESTINATION and $PREVIOUS are on the same partition (btrfs), so hard links are possible. -- Cheers / Saludos, Carlos E. R.

[opensuse] Audio conversion question
by Carlos E. R. 07 Aug '19

07 Aug '19

Hi, I have a bunch of audio files with extension aac. I want to use them on the car, so I'm trying to convert to mp3. I'm using soundconverter, which seems easy to do - but the results are not what I expect (output trimmed to avoid wrap: 812618 0001 -- Eartha Kitt - Je Cherche un Homme.aac 2737704 0001 -- Eartha Kitt - Je Cherche un Homme.mp3 493130 0002 -- Laura Fygi - Quelqu'un m'aimera.aac 2229610 0002 -- Laura Fygi - Quelqu'un m'aimera.mp3 1156682 0003 -- Coralie Clement - Samba de Mon CSur qui Bat.aac 5229555 0003 -- Coralie Clement - Samba de Mon CSur qui Bat.mp3 As you can see, the resulting mp3 files are way bigger than the originals. What can I do? -- Cheers / Saludos, Carlos E. R. (from 15.0 x86_64 at Telcontar)

[opensuse] Microsoft Intune
by Roger Oberholtzer 07 Aug '19

07 Aug '19

Anyone have any experience with Microsoft Intune from a Linux client? Just got a message from IT that this is how e-mail will be managed from now on. On phones, for example, it can only be accessed via Outlook. The existence of a web interface is unclear. No mention of Linux client support: https://docs.microsoft.com/en-us/intune/supported-devices-browsers Sigh. -- Roger Oberholtzer -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] Compressed filesystems?
by Carlos E. R. 06 Aug '19

06 Aug '19

Hi, What filesystems do we have with transparent compression? Read/write, of course. I intend to create a compressed backup external disk (Leap 15.0) I know of btrfs and zfs. zfs is not supported officially on openSUSE, that's a con. I read on some sites not to use zfs on single drives (<https://www.ixsystems.com/community/threads/single-drive-zfs.35515/#post-21…>) «Well, the CTO of iXsystems said something like "single disk ZFS is so pointless it's actually worse than not using ZFS". Technically you can do deduplication and compression. But there is no protection from corruption since there is no redundancy. So any error can be detected, but cannot be corrected. This sounds like an acceptable compromise, but its actually not. The reason its not is that ZFS' metadata cannot be allowed to be corrupted. If it is it is likely the zpool will be impossible to mount (and will probably crash the system once the corruption is found). So a couple of bad sectors in the right place will mean that all data on the zpool will be lost. Not some, all. Also there's no ZFS recovery tools, so you cannot recover any data on the drives. You cannot use the standard recovery tools that are designed for NTFS, FAT32, etc either. They don't work correctly.» Other alternatives? btrfs seems to support it well. <https://btrfs.wiki.kernel.org/index.php/Compression> Then, what compression method to use? Default is zlib, says the wiki. «There's a speed/ratio trade-off: ZLIB -- slower, higher compression ratio (uses zlib level 3 setting, you can see the zlib level difference between 1 and 6 in zlib sources). LZO -- faster compression and decompression than zlib, worse compression ratio, designed to be fast ZSTD -- (since v4.14) compression comparable to zlib with higher compression/decompression speeds and different ratio levels (details) The differences depend on the actual data set and cannot be expressed by a single number or recommendation. Do your own benchmarks. LZO seems to give satisfying results for general use.» That seems to point to ZSTD. The wiki says there are 15 compression levels with ZSTD, but does not say which is the default or describe the expectations for each level. Points to a "details" link. Maybe level 1 would do. I do not want really high compression ratio, I prefer speed because backups are large. And things like email compress very well, anyway. Ideas? -- Cheers / Saludos, Carlos E. R.

[opensuse] Need help app icons on mate panel
by JD 06 Aug '19

06 Aug '19

Sorry for repeating my question... Leap 15.101 Running Mate DT (with all the latest updates. All apps do not show Active Icons on the Mate panel. So, if and when I iconify an app, I have no way of de-iconifying it, because there is no icon for me to click on. Can anyone shed some light on this please?

[opensuse] libreoffice LibreLogo macro bug
by Dave Howorth 06 Aug '19

06 Aug '19

There's apparently a bug in LO that can run arbitrary code. https://www.theregister.co.uk/2019/07/30/libreoffice_macro_virus/ Does anybody know whether this has been or will be patched for Leap 15.0 (LO 6.1.5.2)/ i.e. an openSUSE back patch since LO aren't fixing AIUI. LibreLogo appears to be part of the libreoffice-pyuno package. Is there any way to disable it, or just remove the /usr/lib64/libreoffice/share/Scripts/python/LibreLogo directory?

[opensuse] rsync --exclude --include question
by Carlos E. R. 06 Aug '19

06 Aug '19

I have: OPTIONS="--archive --acls --xattrs --hard-links --sparse --stats --human-readable " rsync $OPTIONS --password-file /root/cripta/keys/rsync.secrets \ --exclude=/lost+found --exclude=/dev --exclude=/sys --exclude=/proc --exclude=/run \ --exclude=/data --exclude=/mnt --exclude=/other --exclude=/media --exclude=/var/lib/samba/lock/ --exclude=/var/run/ \ --include=/data/storage_** \ / root@Isengard::MyBook_Telcontar/001 It is failing, /data/storage_** is not included. What is the proper way in this tree: /data/something/* /data/somethingelse/* /data/somethingmore/* /data/somethingevenmore/* /data/storage_a/* /data/storage_b/* to copy /data/storage_a, /data/storage_b, and ignore all the rest, without explicitly listing all the rest? I thought that --exclude=/data --include=/data/storage_** would do it. The manual is very confusing to me. -- Cheers / Saludos, Carlos E. R. (from 15.0 x86_64 at Telcontar)

[opensuse] btrfs compression report - how do I interpret it?
by Carlos E. R. 05 Aug '19

05 Aug '19

As commented on another post, I have done a backup of my main computer using rsync to another machine with a btrfs formatted hard disk of 8TB. Mounted with compression. Info: <https://btrfs.wiki.kernel.org/index.php/Compression> Isengard:~ # mount -v | grep btrfs /dev/mapper/cr_my_book_tlcntr on /mnt/BookTelcontar type btrfs (rw,relatime,lazytime,compress=zlib,space_cache,subvolid=5,subvol=/) Isengard:~ # Finally, I have found "compsize" - maybe I mistyped the name before: +++............... How can I determine compressed size of a file? compsize takes a list of files on a btrfs filesystem and measures used compression types and effective compression ratio: https://github.com/kilobyte/compsize There is a patch adding support fort that, currently it's not merged. You can kind of guess at its compressed size by comparing the output from the df command before and after writing a file, if this is available to you. ...............++- This is the report: Isengard:~ # time compsize --bytes /mnt/BookTelcontar/001/ Processed 3415745 files, 7871897 regular extents (8084571 refs), 1896373 inline.

[opensuse] Kmail message decryption fails on large messages
by Tobias 05 Aug '19

05 Aug '19

Hello, I am using kmail on tumbleweed and experience this strange behavior: When I get very large encrypted text-only emails (> 1mb ) kmail fails to decrypt them. "Please wait while the message is being decrypted..." is being shown forever (kmail does not crash, though). Decryption of smaller emails or emails with attachments (can be larger) from same or other senders is no problem. Also decryption of the same messages with thunderbird/enigmail or with evolution is no problem. And of course saving the gpg encrypted part and manually decrypting it works as well. Any ideas what might cause this problem? Thank you, Tobias -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] media check errors
by gumb 04 Aug '19

04 Aug '19

Installing Leap 15.1 on a new machine, and for the first time ever I'm using USB instead of DVD (since there is no optical drive). I've downloaded the ISO, first by torrent, run sha256sum in the terminal, all is good. When I start the installation, by force of habit I go to the extra menu and choose media check. Whether that is designed for USB as well as DVD I don't know, but it starts off anyway. To my surprise, when it finishes it says there is an error. Back on the Leap 42.3 machine that I downloaded the ISO on, I decide to go into YaST > Software > Media Check, then Check ISO File... (on the ISO file on hard disk, not the USB stick). It also produces an error: Medium: DVD1 Size: 3961474 kB Result: sha256sum wrong I downloaded it again, direct this time instead of torrent. Ran sha256sum in the terminal, all fine. Ran the YaST Media Check again. Same error. WTF? Should I proceed with installation? (I'm going to anyway because this seems like horseclod, but why does it happen?) gumb -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org
