 conr | ElvishJerricco: how do you remove the filesystem name and label with cfdisk? | 21:43:25 |
 ElvishJerricco | oh, cfdisk is just a partitioning tool. It doesn't format the partitions themselves | 21:43:56 |
| conr | still shows
Filesystem UUID: 1529979882388306283 │
Filesystem LABEL: jjpool │
Filesystem: zfs_member
| 21:43:59 |
| conr | so use fdisk? | 21:44:14 |
| ElvishJerricco | no fdisk is just a CLI version of cfdisk | 21:44:24 |
| ElvishJerricco | Just use wipefs to actually wipe a partition | 21:44:29 |
| conr | i think i have to instlal it | 21:44:42 |
| conr | * i think i have to install it | 21:44:48 |
| ElvishJerricco | don't think so? | 21:44:48 |
| conr | oh right | 21:45:05 |
| conr | so i want to wipe all the magic strings with -a? | 21:47:37 |
| ElvishJerricco | conr: that's what I do | 21:49:32 |
| conr | hmm still shows the same name and label in cfdisk. | 21:54:59 |
| conr | it did ask me witch filesystem i wanted, gpt, fat, etc... | 21:56:16 |
| conr | * it did ask me which filesystem i wanted, gpt, fat, etc... | 21:56:25 |
| ElvishJerricco | 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 | well, on what used to be the partitions | 21:59:07 |
| ElvishJerricco | so when you create the same partition table again they'll get "resurrected" so to speak | 21:59:24 |
| conr | i deleted the partitions with cfdisk first | 21:59:37 |
| conr | then tried wipefs. | 21:59:42 |
| ElvishJerricco | right, that's just wiping the partition table | 21:59:48 |
| ElvishJerricco | so when you put back the same partitions, their contents are still the same as they used to be | 22:00:00 |
| ElvishJerricco | you need to wipefs the individual partitions first | 22:00:10 |
| ElvishJerricco | then you can repartition the disk (or not, if you already like the partition layout) | 22:00:21 |
| conr | what if i can't remember layout? | 22:01:00 |
| conr | i'll just recreate the zpool then destroy it | 22:09:13 |
| conr | ElvishJerricco: i am doing it wrong? should the type be crypt? | 23:42:49 |
