|
|
Hello,
I installed a zfs stripe on one of the partitions of my disk, just because I need to access that partition r/w when I boot OSX.
Now, gparted shows the whole disk occupied by that zfs partition.
However, parted correctly shows:
Code: | # parted -l /dev/sda
Model: ATA Crucial_CT2050MX (scsi)
Disk /dev/sda: 2050GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:
Number Start End Size File system Name Flags
1 20.5kB 210MB 210MB fat32 EFI System Partition boot, esp
2 210MB 175GB 174GB MACOSX
3 175GB 238GB 62.9GB ext4
8 667GB 685GB 17.2GB linux-swap(v1)
6 685GB 792GB 107GB ext4
7 792GB 834GB 41.9GB ext4
4 834GB 2050GB 1217GB |
and fdisk:
Code: | # fdisk -l
Disk /dev/sda: 1.9 TiB, 2050408636416 bytes, 4004704368 sectors
Units: sectors of 1 * 512 = 512 bytes

Disk identifier: ....... (obfuscated)
Device Start End Sectors Size Type
/dev/sda1 40 409639 409600 200M EFI System

Partition table entries are not in disk order. |
Gparted is very convenient for confortably manipulating partitions and I would like to have it back. Can anybody help, please?
TIA

Can you explain it further?
Which version of parted?
Maybe test the Live CD of Gparted. Here: https://gparted.sourceforge.io/ |

I'm not seeing any zfs partitions here, they should be of type BF01. _________________

Just a wild guess: check if gparted reads GPT partition table too... or MBR.

Hello,
Thank you both for replying.
I've downloaded gparted-live-0.31.0-1-amd64.iso, dd to a usb stick but it hangs on boot, probably because my mac has dual gpu's, which creates a mess on linux boot. For booting gentoo, I have to switch-off the radeon gpu and boot with the integrated intel, tweaking a few kernel parameters that I had a lot of trouble to discover.
Anyway:
Code: | [I] sys-block/gparted
Available versions: 0.27.0 ~0.28.1 0.29.0 {btrfs cryptsetup dmraid f2fs fat hfs jfs kde mdadm ntfs policykit reiser4 reiserfs udf xfs}
Installed versions: 0.29.0(18:20:13 01/05/18)(policykit -btrfs -cryptsetup -dmraid -f2fs -fat -hfs -jfs -kde -mdadm -ntfs -reiser4 -reiserfs -udf -xfs)
Homepage: http://gparted.sourceforge.net/
Description: Gnome Partition Editor
[I] sys-block/parted
Available versions: 3.2-r1^t ~3.2-r2^t ~3.2_p19-r1^t (~)3.2_p20-r1^t {+debug device-mapper nls readline selinux static-libs}
Installed versions: 3.2_p20-r1^t(13:54:05 01/05/18)(debug nls readline -device-mapper -selinux -static-libs)
Homepage: https://www.gnu.org/software/parted
Description: Create, destroy, resize, check, copy partitions and file systems |
And:
Code: | # zpool status
pool: zmac
state: ONLINE
status: Some supported features are not enabled on the pool. The pool can
still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
the pool may no longer be accessible by software that does not support
the features. See zpool-features(5) for details.
scan: none requested
config:
NAME STATE READ WRITE CKSUM
zmac ONLINE 0 0 0
sda4 ONLINE 0 0 0
errors: No known data errors
|
So, no doubt the zfs partition exists. I don't know why the type does not show.
I could upload a picture of gparted somewhere, please just give me a link.
Rgds,
jss |

So it's sda4... okay. That said, I would agree that it looks fine in parted and fdisk aside from the wrong type being used. Not sure why gparted would see this wrong, although I did see that fdisk says your partition table isn't ordered correctly. If that's the cause I'd say that's a bug in gparted.
Do you have another gui program installed like gnome-disks? I'd be interested to see if they see it wrong too. _________________

The actual version of Gparted is 0.32.0.
Maybe this version works.
And your partition table is jumbled. |

gparted probably is behaving the way it is because of the use flags that were enabled when it was compiled.
parted is a different critter entirely
Edit to add: and I'm not even sure if gparted would ever show zfs properly as there isn't a use flag for it.

@guitou: sorry, I didn't see your post timely. And how do I do that?
Quote: | The actual version of Gparted is 0.32.0 |
@Keruskerfuerst: As far as I read here: https://gparted.sourceforge.io/download.php the latest stable version is 0.31.0-1
And yes, the partition tabled is not ordered but that was never a problem before I made a zfs partition. I have a hunch that the problem remains after I put it in order.
Quote: | Do you have another gui program installed like gnome-disks? I'd be interested to see if they see it wrong too. |
@bunder: Right, just installed gnome-disk-utility and it can see all the partitions, although it says sda4 (zfs pool) is not mounted which is probably correct because it's mounted differently, as far as my knowledge goes. It also says that sda2, my AFPS MacOS partition, is a "zfs_member" which is also probably right because my MacOS also imports this zfs pool.
@site administrators: I never missed so much the possibility of uploading an image; it would save the day.
Quote: | gparted probably is behaving the way it is because of the use flags that were enabled when it was compiled. |
@Anon-E-moose: I could adjust the flags the way you want but first, please explain:
1. Why do I have to turn on btrfs, ntfs and reiserfs considering they are not present on the disk
2. Similarly, why do I have to turn-off a lot of other fs that are not in use?
3. I need policykit to be able to launch gparted without using a sudo terminal. Why do I have to turn it off?
4. I never touched the flags, these are the Gentoo defaults. Are they wrong?
Thank you all for your help and support. Looking forward to your continued interest.
Best rgds,

Those are just flags from my system.
I was just showing the different flags that affect what partitions gparted can handle, fat, xfs, ntfs, etc.
Notice there isn't one for zfs which means it's not likely to work for zfs partitioning.
Edit to add: with a little googling http://www.andybotting.com/zfs-on-linux
Edit to add2: According to gparted website, the most gparted can do is detect the filesystem, it can't read, write, shrink, etc. _________________ PRIME x570-pro, 3700x, 6.1 zen kernel

I was aware of that when I opted for zfs. But it was the only way I had to dual-boot MacOS and Linux on this machine. Either that or I wouldn't be able to use Gentoo at all; not with my data at least.
But I thought, although I couldn't touch the zfs partition, I would be able to manipulate the other partitions with gparted, as I did before (excluding APFS of course). This is necessary for trying other OS's, so on...
Leaving gparted apart, I'm constrained to console only partition editing which is not very confortable and is sometimes dangerous because errors are not so obvious as with a gui.
Edit: concerning the link you posted, forgive the off-topic, I also have an HP Proliant home server but mine is a N54L (a bit more powerful, also a bit more power waster) but it's running FreeBSD (FreeNAS) 24/7 very peacefully, zfs mirror, no problems whatsoever, running automatic backups for all the machines in-house, tvheadend recording server, multimedia server, and above all I usually can forget it exists; it's my concept of wonderful.
Best regards,
jss

You can use gparted on other filesystems, just not on zfs partitions.
It sounds like you might have used the whole disk for your stripe. Is that possible? _________________ PRIME x570-pro, 3700x, 6.1 zen kernel

No, look at the parted and fdisk outputs on my first post.
Otherwise, how could I be writing this off my Gentoo system residing on another ext4 partition of the same disk? |

Just a thought off the top of my head.
gparted should recognize the other partitions even if it can't work with the zfs one,
but I'm not sure how the version you were trying was compiled and with what flags.
If it didn't understand fat, the 1st partition, it might not understand the rest.
But this is all a wild assed guess. _________________ PRIME x570-pro, 3700x, 6.1 zen kernel

Thank you for keep trying.
Unfortunately I guess that's not it because this started right after I made the zfs partition and gparted worked perfectly until then and was definitely not rebuilt or upgraded in the meanwhile. I used it extensively to move and resize partitions just before making the zfs one; it started right after, as I said.
I guess I'll have to get deeply acquainted with parted for the future.
