The server had 2x RAIDZ-1 pools - each with 4x 16TB drives (ashift=12). We have a Supermicro server with 8x 16T drives running Debian 10 and and OpenZFS 0.8.6. Wondering if anyone else has noticed the same behavior. After the upgrade, we are noticing much higher compression ratios when switching from lz4 to zstd.
#OPENZFS YOSEMITE UPGRADE#
Last week we decided to upgrade one of our backup servers from OpenZFS 0.8.6 to OpenZFS 2.0.3.
#OPENZFS YOSEMITE FULL#
Did this log_spacemap feature get backed out perhaps? Do I need to pick between a full backup and recreation of the pool or manually building zfs from git to get the feature? Or can I get the old 2.0.0 packages somehow? I've uninstalled and reinstalled multiple times to make sure it really is running zfs 2.0.4 and not 0.8.x or something. Required feature(s), or recreate the pool from backup. "-o readonly=on", access the pool on a system that supports the ItĬannot be accessed in read-write mode because it uses the followingĬom.delphix:log_spacemap (Log metaslab changes on a single spacemap and flush them periodically.)Īction: The pool cannot be imported in read-write mode. Status: The pool can only be accessed in read-only mode on this system. When I got back I had to reinstall the zfs modules, this time getting 2.0.4 from the zfs-testing yum repository but when I come to import the dataset, I get: state: UNAVAIL I was away for a couple of weeks and a colleague had put kernel updates on the machine. I had created a fresh pool with a special vdev. This worked fine for some months and there were no issues. In January, I enabled the zfs-testing repository on a RHEL 8 system and upgraded OpenZFS from it to get version 2.0.0. Does it do a checksum scan on all the blocks for each of the txg's? What does the -X option do under the hood. So how long should my command take to run? Is it going to go through all the data? I don't care about partial data loss for the files being transferred at that time, but I'm really hoping I can get all the older files that have been there for many weeks.ĮDIT: Another question. The difference is the first pool was transferring a large number of files between one dataset to another. I have another machine with 8TB x 7 drives and that pool is fine. The pool is 14TB x 8 drives setup as RAIDZ1. It's been running for 8 hours, and it's still running. Right now I'm running "sudo zpool import -nFX mypool". Tried "sudo zpool import -F mypool", and the same error. I tried importing the pool and it gave an I/O error and told me to restore the pool from a backup. All the stuff is hooked up to a surge protector. I’m going to attempt to use an encrypted sparse bundle on ZFS.Lightning hit the power lines behind our house, and the power went out. I’ve tried using FileVault + ZFS and it was terribly slow. You’ll notice I didn’t use FileVault under my zpool. With the output that looked like this now: 1 I also verified my disk partitions to make sure: 1 I took note of the IDENTIFIER of the partition I want to erase/use as ZFS: in my case disk0s4 and changed the label to ZFS with: 1ĭiskutil eraseVolume ZFS %noformat% /dev/disk0s4 Then I installed OpenZFS_on_OS_X_1.3.0.dmg from OpenZFS On OS X 1ģ: Apple_Boot Recovery HD 650.0 MB disk0s3Ĥ: Microsoft Basic Data tank 500.4 GB disk0s4 This is the partition I will relabel/erase.

#OPENZFS YOSEMITE MAC#
In the output below, you’ll notice I have a mac partition where OS X 10.10 Yosemite is installed. I ran this to check my disk partitions: 1 I don’t use this anymore, but kept the instructions here for future reference
