Duplicating a zpool

Leave a Comment / DELL, Disk Cloning, Disks, FreeBSD, hardware, Open Source, R720, ZFS / By /

I have these boot drives, I want to copy them to another. They both happen to be zroot and bootable. I booted from mfsBSD and imported both new and old zroot, using the pool ID shown by zpool import -N. root@mfsbsd:~ # zpool import -N pool: data01 id: 2668514456528412656 state: ONLINE action: The pool can be imported using its name or numeric identifier. config: data01 ONLINE mirror-0 ONLINE gpt/S59VNS0N809087J_S00 ONLINE gpt/S59VNJ0N631973D_S01 ONLINE mirror-1 […]

Creating a 4 drive ZFS zpool: stripe over mirrors

4 Comments / Disks, hardware, Open Source, ZFS / By /

In this post, I am creating a 4 drive ZFS pool consisting of two mirror. In this post: I’m booting from mfsBSD 12.1 ZFS Creating partitions On FreeBSD, it is convention to create partitions. It is not necessary, but I don’t use all the space in case a future replacement drive is slightly smaller than these drives. NOTE: I am not, but have not confirmed that this is no longer a problem in

replacing an existing zroot with a proper zroot

Leave a Comment / bectl, Disks, FreeBSD, hardware, Open Source / By /

I wrote this post late one night while pondering how to solve this problem. I may have solved it with much less effort. I want to copy a zroot from old drives to new drives. The new drives are in a test box of mine. Once the new drives are configured, I will replace the existing mirror with them. Not shown here, I have already installed FreeBSD 12.1 on the new drives. I

This post has been replaced by a newer post. For future reference, this is the knew server … oh wait, I think it’s this server which is was mounted in the 4U chassis mentioned in this post. It runs a few jails, including Bacula regression testing services. It is now mounted in a SuperChassis 846E16-R1200B This is the previous post for this system configuration. Photos of the assembly.

zpool degraded – one drive missing from system

Leave a Comment / Disks, FreeBSD, Open Source, ZFS / By /

I rebooted knew yesterday for upgrades. When it came back, the main storage zpool was degraded: Is the drive alive? The drive is not listed at all in /var/run/dmesg.boot. I keep a list of the expected drives in /etc/periodic.conf, for use by a Nagios check: [dan@knew:~] $ /usr/sbin/sysrc -nf /etc/periodic.conf daily_status_smart_devices /dev/da22 /dev/da21 /dev/da20 /dev/da19 /dev/da18 /dev/da17 /dev/da16 /dev/da15 /dev/da14 /dev/da13 /dev/da12 /dev/da11 /dev/da10 /dev/da9 /dev/da8 /dev/da7 /dev/da6 /dev/da5 /dev/da4 /dev/da3 /dev/da2 /dev/da1

Creating a drive-bay map

Leave a Comment / Disks, FreeBSD, Open Source, ZFS / By /

When the time comes to replace a drive, it is very nice to know which drives is missing. I created this drive map to help me figure out which drive disappeared. I created this drive-bay map using a combination of: zpool status sesutil map lsblk camcontrol /var/run/dmesg.boot I have not included /var/run/dmesg.boot here. If you click on this image, you’ll see a larger version which is easier to read. I went through sesutil

Migrating all your iocage jails to a new host

Leave a Comment / DELL, Disks, FreeBSD, hardware, iocage, Jails, Open Source, R710, R720 / By /

In this post, I’m not exporting an iocage jail to another host. I am moving the entire iocage instance to another host. This is accomplished by doing a zfs export on the zpool, moving the drives to a new system, and doing a zfs import. The drive migration is covered in a previous post. In this post: FreeBSD iocage old host: R710 – r710-01 new host: R720 – r720-01 The first power The

Migrating drives and the zpool from one host to another.

Leave a Comment / DELL, Disks, hardware, Open Source, R710, R720, ZFS / By /

Today is the day. Today I move a zpool from an R710 into an R720. The goal: all services on that zpool start running on the new host. Fortunately, that zpool is dedicated to jails, more or less. I have done some planning about this, including moving a poudriere on the R710 into a jail. Now it is almost noon on Saturday, I am sitting in the basement (just outside the server room),

Installing internal PCI Slot SSD drive enclosures in a Dell R720

Leave a Comment / DELL, Disks, hardware, R720 / By /

I like to build systems that boot using drives directly connected to the M/B. No HBA, no SATA cards, etc. I like the simplicity involved. Sometimes that target is hard to achieve. The first step to configuring the R720 was upgrading the firmware. I spent time on hardware selection, including power and data sources. I also spent time looking at NVMe booting, but abandoned that idea. Earlier this week, enough hardware had arrived
