[opensuse-factory] SSD erased after fstrim
Hi, I have some strange behavior while testing Tumbleweeed over the last two weeks. I have seen it with different versions, also with the latest 20160105 a few minutes ago. When doing a 'fstrim -v /' and then reboot I get a 'Non-System disc or disk error,...' after that. It looks that the trim command trims a bit more as it should do. I tested that on two different computers with different SSDs. Both show the same fault. I had openSUSE 13.2 installed before I switched to Tumbleweed and there was no problems with fstrim. My disc configuration has no separate home partition, so all is btrfs. My home directory is a btrfs subvolume with snapper timeline snapshots enabled. Don't know if that is related to this issue. Any ideas? Br, Frank -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

not that long ago I've found this post which is horror story. I don't know which model of hdd or ssd you have. https://blog.algolia.com/when-solid-state-drives-are-not-that-solid/ -- Bruno Friedmann Ioda-Net Sàrl www.ioda-net.ch openSUSE Member & Board, fsfe fellowship GPG KEY : D5C9B751C4653227 irc: tigerfoot -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

I have the same problem with a oldish samsung SSD. it is not that the disk is wiped (at least in my case) but grub2 installation gets corrupted. reinstalling grub2 from a rescue system "fixes" the problem. I opted just to just "not do that then".. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

That revived also my machine, thanks for the hint. I observed that behavior on both discs I have: ata1.00: ATA-10: Crucial_CT250MX200SSD1, MU03, max UDMA/133 scsi 0:0:0:0: Direct-Access ATA Crucial_CT250MX2 MU03 PQ: 0 ANSI: 5 ata10.00: ATA-9: Samsung SSD 840 EVO 1TB, EXT0DB6Q, max UDMA/133 scsi 9:0:0:0: Direct-Access ATA Samsung SSD 840 DB6Q PQ: 0 ANSI: 5 Not sure if this problem is related to the discs (both seem to have the same problem, maybe they have the same controller inside) or to the software. When the problem can be fixed by reinstall the bootloader only it looks a bit that the fstrim command is not aware of the bootloader installation location and therefore it is getting trimmed. My setup has the bootloader installed in the root partition. I will do some experiment when it is installed in the MBR. Let's see what happens then.

Of course - that makes total sense. The filesystem basically has no idea what you are doing with unreferenced sectors outside its purview. Which is probably why running fstrim on a volume with a hidden volume (akin to what truecrypt did) would also be a bad idea. I guess the extra /boot partition (for old systems) and /boot/efi saved me from observing it so far, since I hardly see a reason to run trim there :p -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

btrfs explicitly reserves space for bootloader; if btrfs then "trims" this space, it is a serious bug in btrfs. I actually expect any filesystem to trim only space it has allocated and knows about.

I'm still not sure what happened here (and as I understand original state is no more available). "Non-System disc or disk error" is /probably/ output by BIOS; and as far as I understand the only thing BIOS can check is 0xAA55 signature; but this is not changed by reinstalling GRUB (GRUB only rewrites code part in MBR). It may be possible that it is output by INT 18H (some Microsoft MBRs return to it if no bootable partition was found), but then again, installation of GRUB does not change it - unless GRUB location was changed from partition to MBR. So there is unfortunately simply not enough information to make any guess what happened. Before "fixing" it was really needed to collect as much information as possible :( If it is possible to reproduce it I would really love to see - information about GRUB configuration - original MBR and VBR before fstrim - MBR and VBR after fstrim -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Which config files you want to see, or is there a possibility to dump the relevant information somehow?

Which config files you want to see, or is there a possibility to dump the relevant information somehow?

When the problem can be fixed by reinstall the bootloader only it looks a bit that the fstrim command is not aware of the bootloader installation location and therefore it is getting trimmed. My setup has the bootloader installed in the root partition.
Of course - that makes total sense. The filesystem basically has no idea what you are doing with unreferenced sectors outside its purview.
btrfs explicitly reserves space for bootloader; if btrfs then "trims" this space, it is a serious bug in btrfs. I actually expect any filesystem to trim only space it has allocated and knows about.
