![]() Flush /dev/sda with wipefs, then mkswap, swapon, genfstab, don't create a partition in partition with fdisk (in /dev/sda). Solution to the problem - dont't partition the partition, as Scimmia stated. The wipefs command (since v2.31) lists all the offset where a magic strings have been detected. Note that some filesystems and some partition tables store more magic strings on the device (e.g. Can withstand low temperature down to -50 deg C. Can withstand high temperatures up to +80 deg C. gpart recover can (sometimes) bring back a valid GPT setup, copying the backup GPT to the primary, and then gpart destroy can be used to remove both. Super silent even on heavy rain and snow. Then some other partitioning, usually MBR, is installed without removing the GPT, so a new table overwrites the primary GPT at the start of the disk but leaves the backup table still present at the end. Why choose GPT Super Silicone Wiper Blades. In this case the wipefs scans the device again after each modification (erase) until no magic string is found. wipefs calls the BLKRRPART ioctl when it has erased a partition-table signature to inform the kernel about the change. features: windshield wiper, wipers, windscreen wiper, front windshield wiper, windshield wipers. Dry-run wipefs on existing LVM2 member or empty disk/partition. The list or individual types can be prefixed with 'no' to specify the types on which no action should be taken. More than one type may be specified in a comma-separated list. When option -a is used, all magic strings that are visible for libblkid are erased. page.-t, -types list Limit the set of printed or erased signatures. The answer that finally made me understand the problem is contained in the V1del's post. The wipefs command (since v2.31) lists all the offset where a magic strings have been detected. How could swap partition mess my brightness up? Could you give me a little help with understanding what I need to do next to fix it? Unfortunately, my knowledge ends at this very point. I can live that way or even activate swap manually each time I reboot, but that would be kinda nice if I could have my swap partition activated on load. The last thing that I tried was to comment swap line out in fstab, and it got rid of relevant error messages (brightness thing persisted, though). It works normally if UUID is back at fstab. In order to do so, all we have to do is to launch the utility without specifying any option, but just passing the device we want to analyze as argument. * dev-disk-by\x2dpartuuid-1878cf5f\x2d6b9c\x2d7340\x2d9150\x2db677f351668b.swap loaded failed failed /dev/disk/by-partuuid/1878cf5f-6b9c-7340-9150-b677f35166>Īs an additional bonus, the brightness of the screen went down on boot (can be changed, though). Wipefs can be used not only to erase existing signatures on a device, but also to create a report which includes them without performing any modification.
