@conr:mozilla.orgconr ElvishJerricco: how do you remove the filesystem name and label with cfdisk? 21:43:25
@elvishjerricco:matrix.orgElvishJerriccooh, cfdisk is just a partitioning tool. It doesn't format the partitions themselves21:43:56
@conr:mozilla.orgconr

still shows

 Filesystem UUID: 1529979882388306283                                                                                  │

@conr:mozilla.orgconr so use fdisk? 21:44:14
@elvishjerricco:matrix.orgElvishJerriccono fdisk is just a CLI version of cfdisk21:44:24
@elvishjerricco:matrix.orgElvishJerricco Just use wipefs to actually wipe a partition 21:44:29
@conr:mozilla.orgconri think i have to instlal it21:44:42
@conr:mozilla.orgconr * i think i have to install it21:44:48
@elvishjerricco:matrix.orgElvishJerriccodon't think so?21:44:48
@conr:mozilla.orgconroh right21:45:05
@conr:mozilla.orgconr so i want to wipe all the magic strings with -a? 21:47:37
@elvishjerricco:matrix.orgElvishJerricco conr: that's what I do 21:49:32
@conr:mozilla.orgconr hmm still shows the same name and label in cfdisk. 21:54:59
@conr:mozilla.orgconrit did ask me witch filesystem i wanted, gpt, fat, etc...21:56:16
@conr:mozilla.orgconr * it did ask me which filesystem i wanted, gpt, fat, etc...21:56:25
@elvishjerricco:matrix.orgElvishJerricco conr: did you wipefs the individual partitions or the whole disk? Like wipefs -a /dev/nvme0n1 will just erase the GPT but the file systems on the partitions will remain 21:58:57
@elvishjerricco:matrix.orgElvishJerricco well, on what used to be the partitions 21:59:07
@elvishjerricco:matrix.orgElvishJerriccoso when you create the same partition table again they'll get "resurrected" so to speak21:59:24
@conr:mozilla.orgconr i deleted the partitions with cfdisk first 21:59:37
@conr:mozilla.orgconr then tried wipefs. 21:59:42
@elvishjerricco:matrix.orgElvishJerriccoright, that's just wiping the partition table21:59:48
@elvishjerricco:matrix.orgElvishJerriccoso when you put back the same partitions, their contents are still the same as they used to be22:00:00
@elvishjerricco:matrix.orgElvishJerriccoyou need to wipefs the individual partitions first22:00:10
@elvishjerricco:matrix.orgElvishJerriccothen you can repartition the disk (or not, if you already like the partition layout)22:00:21
@conr:mozilla.orgconrwhat if i can't remember layout?22:01:00
@conr:mozilla.orgconri'll just recreate the zpool then destroy it22:09:13
@conr:mozilla.orgconr ElvishJerricco: i am doing it wrong? should the type be crypt? 23:42:49
