NOTE: we are getting issues after shutdown , then remove ISO file from virtualBox then power on the server. if we attach an ISO file we are safe with our Zpool stuff. and we are creating boot,swap,root partitions on each disks. I'm not able to understand First 5 disks are ONLINE and remaining disks are UNKNOWN state after power off and then power on actually our requirement is to create RAIDZ1/RAIDZ2 with single vdev(upto 5 disks per vdev) if more than 5 or less than 10 disks then those disks(after 5disks) are spare part shouldn't be included any vdev. if we have multiple's of 5 disks then we need to create multiple vdev in a pool example: RAIDZ2 : if total 7 disks then 5 disks as single vdev, remaining 2 disks as spare parts nothing to do. and if we have 12 disks intotal then 2 vdevs (5 disks per vdev) so total 10 disks in 2 vdevs remaining 2disks as spare. RAIDZ1: if we have only 3 disks then we should create RAIDZ1
Here, we wrote a zfs script for our requirements(but currently testing with manual commands). We are able to createRAIDZ2 with a single vdev in a pool for 5 disks. it works upto 9 disks but if we have 10 disks then 2 vdevs are created after power on the same error coming like zfs: i/o error all copies blocked. I was testing the RAIDZ like I'm creating 2 vdevs which have 3 disks per each vdev.its working fine even after shutdown and power on(as says that we are removing the ISO file after shutdown). but the issue is when we create 2 vdevs with 4 disks per each vdev.this time we are not getting error its giving options like we press esc button what kind of options we see those options are coming. if i type lsdev -v(as you said before). first 5 disks are online and the remaining 3 disks are UNKNOWN. FInally, I need to setup RAIDZ configuration with 5 multiples of disks per each vdev. please look once again below commands im using to create partitions and RAIDZ configuration NOTE: below gpart commands are running for each disk gpart create -s gpt ada0 gpart add -a 4k -s 512K -t freebsd-boot ada0 gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0 gpart add -a 1m -s 2G -t freebsd-swap -l swap0 ada0 gpart add -a 1m -t freebsd-zfs -l disk0 ada0 zpool create -o altroot=/mnt datapool raidz2 ada0p3 ada1p3 ada2p3 ada3p3 raidz2 ada4p3 ada5p3 ada6p3 ada7p3 zfs create -o mountpoint=/ -o canmount=noauto datapool/boot mount -t zfs datapool/boot /mnt mount_cd9660 /dev/cd0 /media cp -r /media/* /mnt/. zpool set bootfs=datapool/boot datapool shutdown and remove ISO and power on the server kindly suggest me steps if im wrong On Wed, Feb 17, 2021 at 11:51 PM Thebest videos <sri.chityala...@gmail.com> wrote: > prtconf -v | grep biosdev not working on freebsd > i think its legacy boot system(im not sure actually i didnt find anything > about EFI related stuff) is there anyway to check EFI > > Create the pool with EFI boot: > # zpool create -B rpool raidz c0t0d0 c0t1d0 c0t3d0 > > how can i create pool with EFI > and -B what it refers? > > On Wed, Feb 17, 2021 at 11:00 PM John D Groenveld <groenv...@acm.org> > wrote: > >> In message <272389262.2537371.1613575739...@mail.yahoo.com>, Reginald >> Beardsley >> via openindiana-discuss writes: >> >I was not aware that it was possible to boot from RAIDZ.
