I have installed mdadm (its on portage) but I have not used it, since there is another soultion for this, which I tried first. Andrea posted this wonderful line: mount -o ro,offset=512 /dev/sdb /mnt/xxx which mounts the filesystem by skipping the partitiontable completly. Currently I am rescueing the data. If all is safed, I will tru mdadm... Thank you very much for your help! As soon as there are more information, I will report back. Maybe this can also help others with similiar problems. Cheers!

It's neither. The package installs a kernel (not just sources for the
kernel), like gentoo-kernel-bin, but it does so by building it locally,
just like just about every other package that doesn't have a name ending
in "-bin". On the other hand, gentoo-kernel-bin downloads a precompiled
kernel and just installs it locally, not compiling anything. The
gentoo-sources package also doesn't compile anything, it just dumps some
source code on your system for you to compile outside of portage.
In short:

gentoo-sources| source code | source code
gentoo-kernel | source code | built kernel
gentoo-kernel-bin | built kernel | built kernel

The filesystem starts at sector 1, i.e. 1*512B, so: mount -o ro,offset=512 /dev/sdb /mnt/xxx But while this will allow you to access your data, you will still have a broken disk until you fix the MBR. andrea

Re: [gentoo-user] Trouble with backup harddisks
All the following assuming that the disk was originally partitioned as GPT, but after that exclusively accessed as an MBR disk. PT fdisk (gdisk) version 1.0.5 Caution: invalid main GPT header, but valid backup; regenerating main header from backup! This makes sense since the GPT backup at the very end of the disk would most likely still be intact. gdisk identifies it correctly, but assumes (wrongly) that the data on the disk is governed by the GPT layout. Since the disk was only ever accessed through an operating system that knew solely about MBR, the GPT data meant nothing to it. It happily wrote data past the MBR headers. Because the protective MBR is positioned before GPT information, the primary GPT header was destroyed and most likely overwritten with the file system. See also [1], the actual file system data probably begins somewhere past LBA 0. Caution! After loading partitions, the CRC doesn't check out! Warning: Invalid CRC on main header data; loaded backup partition table. Warning! Main and backup partition tables differ! Use the 'c' and 'e' options on the recovery & transformation menu to examine the two tables. This is because the backup GPT written when first partitioned does no longer match the data present at the very beginning of the disk. If the initial assumption is correct, GPT *must not* be restored. Your modern PC sees the GPT partition type and assumes the existence of a GPT. It should, however, access the MBR layout and interpret the partition marked with the GPT ID as a regular partition. Now, how to fix this? Like Andrea already said earlier: Since the disk is only 1TB, there is no reason to use GPT at all, so your best bet is to use fdisk to make that a standard MBR by changing the partition type from 'ee' to '83'. This would *not* repartition or reformat any data, it would simply tell your modern operating system to access the protective partition as a regular one. It would, however, require writing the new type to disk. What you could do to be more safe here is to take a backup of the first 512 bytes with `dd', then change the partition ID with `fdisk', and try mounting it. If it works, great. If not, you can restore the first 512 bytes of the disk with the backup. "fix manually" scares me...especially because I have no place for 1TB of an image file to with which I can experiment ... Any ideas which could ease my burden and to un-scare my "need to fix it manually" ??? ;) ;) There's a few alternatives: 1) Boot an older system that only understands MBR, and mount the disk there. This was suggested earlier but was dismissed because we assumed the sector size had something to do with it. I do not think this is the case anymore - the old system should be able to read it. 2) Boot a VM with a kernel that only understands MBR, pass USB through to the virtual machine, mount the disk there. 3) Try confirming that there exists file system data past the MBR header. Maybe something like this: # dd if=/dev/sdb of=sdb-data bs=512 skip=1 count=16384 $ file sdb-data As established, the block size is 512 bytes. We skip the first 512 bytes since that is the protective MBR. sdb-data should then contain the first 8MiB worth of actual file system data. The `file' utility can tell you what kind of data it is.

[gentoo-user] sddm-helper and high memory usage
Howdy, I been noticing that sddm is using a lot of memory. In the past, it would use a few hundred megabytes but nothing out of the norm for a GUI command. This is what ps aux shows. USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 19256 1.0 10.3 3443932 3400112 ? S 02:40 6:36 /usr/libexec/sddm-helper --socket /tmp/sddm-auth8e2859d9-6da1-4071-b479-b9caa969c3d8 --id 1 --start /usr/bin/startplasma-x11 --user dale When it did this the other day, I closed all my programs so I could logout, reset and log back in again. After I hit logout, I noticed the little memory usage meter on the bottom of my screen was down to a more normal level. It was already logging me out so to late to stop it. It seems that it dropped after I closed Firefox. I tend to have two profiles running and they use quite a bit of memory on their own. The new thing is sddm using this much as well. Could Firefox have some effect on this?? When I first login, it is using the normal amount of memory. It seems to build up from there. Once it hits around 13 or 14%, it seems to stop using any more. I've let it run for a while and it seems to stop there. I'm pretty sure I upgraded sddm the other day. This is where I'm at right now. kde-plasma/sddm-kcm-5.18.4.1 x11-misc/sddm-0.18.1-r1 Is anyone else noticing this? I would go back a version but it is masked, I'm assuming it has some known issues that may be worse than this. I might add, while I normally switch to the boot runlevel and back again after a upgrade, I did have to shutdown last night. I was trying to replace my UPS batteries. My new batteries are about 1/4" to tall. New set on the way. Anyway, it is doing this even after a fresh power up. I did a bug search on BGO but didn't see anything like this. Any ideas? Dale :-) :-)

What you look for is perhaps {wasstable} which returns the value

I have two external disks of that kind, same product, nearly the same
contents, both have a "fixed case" (sorry...no native speaker...the

Three weeks ago...about...guessed...with my old system.
Because these were backup disks I *NEVER* touch them with
any partitioning tool whatsoever...
It is complete unknown to me, what could have destroyed the
partitioning...

YES! These drives were used as backup and as backup of the backup. I
NEVER touched them with any partitioning tool after I had put a
filesystem and data on it.

Windows? no thank you...all my windows here are transparent and

Joke aside..
No Windows (tm) here. The disks are used only with my Linux box using
ext4 as filesystem.

With my new PC (my old MBR-based system was 12 years old and needed to
be replaced. My kernel became "GPT aware onlu with my new PC.
Everything before was based on MBR.
My new PC can read GPT disks...my system is based on it.

I copied the first 230GB of that disk to an empty partition of my new
system and run "testdisk" on itafter the analysis it came back
with "this partition cannot be recovered" but did not sau. whether the
reason is a partition table, which is broken beyond repair, or simply
due to the incomplete image file...

Re: [gentoo-user] Trouble with backup harddisks
Hi, CONFIG_PARTITION_ADVANCED=y CONFIG_MSDOS_PARTITION=y CONFIG_EFI_PARTITION=y That's all you need. This could be the key. Sector sizes have been changing from 512 to 4096 over many years. If your kernel has been updated to expect/use 4096 byte sectors, it might not be able to read the disk properly. Sector size is only a (fixed) property of a specific block device, not something expected or required by the kernel. Sector sizes other than 512B have been around for ages without any problems, even in consumer hardware (e.g. CDs and DVDs have 2KB sectors). Disklabel type: dos Device Boot StartEndSectors Size Id Type /dev/sdb1 1 1953458175 1953458175 931.5G ee GPT That looks... broken. fdisk is recognizing the disk as MBR (a GPT disk would have "Disklabel type: gpt"), but the partition table is a protective MBR, which makes no sense in a non-GPT disk. My guess is that this disk was at some time partitioned with GPT (possibly it came that way from WD?), but then it was only used in machines with no kernel support for GPT. Such a machine will happily treat that as a normal MBR and allow you to access the protective entry as a normal partition, which means you can create a filesystem on it and fill it with data, destroying the GPT structures. A GPT-aware kernel on the other hand will recognize that as a protective MBR and it will ignore it --but since the disk does not contain any valid GPT structures, it will not show any partitions. Try running "gdisk -l /dev/sdb"; for a valid GPT disk it will say: Partition table scan: MBR: protective BSD: not present APM: not present GPT: present If that's not the case and you have no GPT, you will have to fix things manually. Since the disk is only 1TB, there is no reason to use GPT at all, so your best bet is to use fdisk to make that a standard MBR by changing the partition type from 'ee' to '83'. andrea

As far as I know the kernel still uses 512 bytes internally [1], and I
do not recall having seen an option that enables or disables support for
512/4K sectors.
That said, the problem may well be stemming from a sector size
discrepancy, but as I understand it, it would have to do with how and
when the partition table was created. That is, like described in [2],
some USB enclosures seem to be a bit overzealous with obscure features,
and might take eight disk sectors and bundle them together into one 4K
sector.
If the disk was partitioned in the exact same enclosure, and is read
from the exact same enclosure right now, there shouldn't be any
problems. Is this the case, Meino?
Also, when did you last access the drives successfully, and with which
system?

Interestingly, this reads *exactly* like the Protective MBR [3] that GPT
has. That is, the disklabel type is DOS whilst the partition ID is EE.
There's a single partition that spans the entire drive (and it's also
seemingly not aligned properly - usually you see Start at 2048).
As a comparison, here's the output from fdisk for the Protective MBR
from one of my GPT drives:
Disklabel type: dos
Disk identifier: 0x
Device Boot StartEndSectors Size Id Type
/dev/sdc1 1 4294967295 4294967295 2T ee GPT
I'd assume that the missing disk identifier here is coming from
different tools writing the protective MBR differently.
With that said, are you absolutely certain that you did not partition
this drive with GPT instead of MBR? Did you do the partitioning in
something like fdisk (which asks you specifically what you want), or
some other application? Did you maybe format this drive on a Windows
system?
I'm not one to discount entirely strange things happening, but I have
never before seen a proper MBR laid out like a protective MBR. Indeed it
would be quite impossible to have systems access data through such a
table, since the partitions are hidden within that one huge contiguous
block.
Ordinarily I'd point to fdisk not reading the partition table properly,
but it seems that although your kernel has support for GPT, it doesn't
seem to see the partitions either (assuming a proper GPT exists at all).
Do you have some other GPT drives you can access successfully?
I'd say that this requires some more forensic work. Perhaps extracting
the first few megabytes of the disk and seeing whether there's a proper
GPT or not. This would of course require manual work.
A few more things to try:
To see what the kernel uses for a particular disk, you can run the
following: cat /sys/block/sdb/queue/{physical,logical}_block_size
fdisk takes a sector size with -b, --sector-size (should be
non-destructive as long as you don't write anything, but I am not sure).
Also, fdisk has a compatibility mode for dos with -c=dos. Might be worth
a short.
fdisk should support GPT starting with util-linux 2.23, but you can also
try gptfdisk (it's in the tree).
Hope this helps.

More often than not some early degradation causes random crashes, when under load, rather than complete blackout. It is not easy to test a PSU without an oscilloscope, but you could look at the MoBo voltages with a multimeter to see if they're broadly within limits and don't drop off too much when a load in placed them. Personally I don't bother measuring voltages. If you take the PSU out of the case and visually inspect its capacitors you may find some have domed tops, an indication they have overheated and are on their way out. A few pennies would buy you a bag of replacements which you can solder in to restore the PSU to its original performance. It used to be Panasonic capacitors were better made and had higher ratings, but I don't know what brands can claim better quality of manufacture these days. Burned resistors are an indication of catastrophic surges, although I have replaced resistors and capacitors on a cheap PSU which burnt out when sheet lightning hit our area one year and worked fine for years after that. Of course, if the problem is with the video card, the PSU won't fix your problem. signature.asc Description: This is a digitally signed message part.

I like playing games and noticed with current card that FPS is low on a lot of games. I have tried to get a balance between not paying too much and specs of monitor (2560x1440 @60 fps). According to GPU check I should get max of 80 fps @ 1440. So thought I would have some left in the bank with 5600 XT. I'll check CPU to GPU rate. There's too much choice and now a little worried that next card might not work again. John

Where in the kernel this update is made? I cannot remember to have configured such a thing manually... Changing the partitiontable in any way is risky to the data I think...I am very unsure to do this. I have access to an old kernel / system and can boot it. But than I have the same problem another way around: I can no longer access my new system ... due to the different sector size Are there any other ways to fix this problem? Cheers! Meino

The other thing is try using gdisk (or that could be fdisk under another name :-( But some partitioning schemes can write a GPT with protective MBR - if you can find something that will take the MBR and write it as a GPT that might help, too.

[gentoo-user] Trouble with backup harddisks
Hi, recently I switched from the old MBR-scheme to GPT on my new PC. I have two external USB-harddisk, which were partioned/formatted with a MBR-scheme/MSDOS partition (but were never used to boot from. They are pure data containers). When I connect these to my new PC, only the device is shown: /dev/sdb, /dev/sdc. The kernel is configured (beside other things) as follows: # # Partition Types # CONFIG_PARTITION_ADVANCED=y # CONFIG_ACORN_PARTITION is not set # CONFIG_AIX_PARTITION is not set # CONFIG_OSF_PARTITION is not set # CONFIG_AMIGA_PARTITION is not set # CONFIG_ATARI_PARTITION is not set # CONFIG_MAC_PARTITION is not set CONFIG_MSDOS_PARTITION=y # CONFIG_BSD_DISKLABEL is not set # CONFIG_MINIX_SUBPARTITION is not set # CONFIG_SOLARIS_X86_PARTITION is not set # CONFIG_UNIXWARE_DISKLABEL is not set # CONFIG_LDM_PARTITION is not set # CONFIG_SGI_PARTITION is not set # CONFIG_ULTRIX_PARTITION is not set # CONFIG_SUN_PARTITION is not set # CONFIG_KARMA_PARTITION is not set CONFIG_EFI_PARTITION=y # CONFIG_SYSV68_PARTITION is not set # CONFIG_CMDLINE_PARTITION is not set # end of Partition Types CONFIG_BLOCK_COMPAT=y CONFIG_BLK_MQ_PCI=y CONFIG_BLK_MQ_VIRTIO=y CONFIG_BLK_PM=y dmesg shows this: [14617.672363] usb 2-2: New USB device found, idVendor=1058, idProduct=25a2, bcdDevice=10.21 [14617.672364] usb 2-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [14617.672364] usb 2-2: Product: Elements 25A2 [14617.672365] usb 2-2: Manufacturer: Western Digital [14617.672366] usb 2-2: SerialNumber: 575844314132383959393934 [14617.681660] usb-storage 2-2:1.0: USB Mass Storage device detected [14617.681737] scsi host10: usb-storage 2-2:1.0 [14618.725450] scsi 10:0:0:0: Direct-Access WD Elements 25A21021 PQ: 0 ANSI: 6 [14618.725594] sd 10:0:0:0: Attached scsi generic sg1 type 0 [14618.728090] sd 10:0:0:0: [sdb] Spinning up disk...

I was hoping for a 'system' level solution. I think it was consolekit that, when a user tried to shutdown while another user was logged presented a window asking for root password to execute the command. (ESC would let it continue and do the shutdown anyway, so it was not really working). I'll go for the manual way. Thanks, Raffaele

What are the tasks, which put a heavy load on your PC/graphicscard and which you are do regularily? Do you do a lot of rendering (Blender for example) or video (re-)encoding? Do you AI related things (tesorflow for example)? Or is gaming you main application? Furthermore: You CPU must fit your graphicscard performancewise. It makes no sense to choose "a performance beast" and to combine it with a "entry level being". The fastest graphicscard can onlu as fast, as data are coming from the CPU and vice versa. On the internet you find a combination of the Ryzen 5 3600 with one of the nvidia RTX 20[678] SUPER cards. The RTX 2060 SUPER comes with 8GByte of video ram instead of 6 GBYte of the RTX 2060.
