data04: DEGRADED – oh and have I mentioned WatchGoose?

Leave a Comment / nvme, ZFS / By /

I saw this today in my logs on r730-01. It looks similar to a previous DEGRADED even back on July 2. In this case, the device is S7KGNU0Y915666E, not S7KGNU0Y912955D as it was back then. The zpool status is: [12:16 r730-01 dvl ~] % zpool status data04 pool: data04 state: DEGRADED status: One or more devices have been removed. Sufficient replicas exist for the pool to continue functioning in a degraded state. action:

data04: DEGRADED

Leave a Comment / nvme, ZFS / By /

This morning I noticed this in the logs after doing some pkg upgrade. I was mainly updating openvpn, but in that operation, fail2ban was removed (because I went from python312 to python314). I noticed it missing on one host: I ran this grep to verify fail2ban had been removed from another host: Well, this host doesn’t run fail2ban, but those messages are “interesting”. How much is nvme mentioned in the logs? [12:31 r730-01

r730-01: storage plan

Leave a Comment / Disks, hardware, nvme, R730 / By /

Following on from What will I do with those 2 x 1TB drives?, I received a fantastic suggestion from Mike Gerdts. Do more bifurcation. Buy an ASUS HYPER M.2 X16 GEN 4 CARD and put 4x NVMe devices on each one. I can be adding 8 more storage devices to the chassis. I see posts from people using this card in a Dell R730xd – The host in question is a Dell R730.

Let’s tally up. For reference, this is one of a series of posts regarding compression testing on zpools: Experimenting with compression off Experimenting with compression=lz4 Experimenting with compression=zstd Compression results – you are here Samsung-SSD-870 4TB SSD For the Samsung-SSD-870 4TB SSD no compression we had: 2:34 = 154s 2:32 = 152s 2:30 = 150s 3:52 = 238s 4:46 = 286s 4:16 = 256s 4:15 = 255s 4:15 = 255s 4:49 = 289s

GEOM: nda1: the primary GPT table is corrupt or invalid

When I destroyed the zpools when I was done with zstd compression testing, these errors appeared in /var/log/messages: You’d be shocked to learn these messages appear when creating a zpool with those devices: [12:21 r730-01 dvl ~/tmp] % sudo zpool create Samsung-SSD-980-PRO-geom-issues mirror /dev/nda1 /dev/nda2 re: Background: these two devices were part of a zpool before I started playing with them. They had partitions on them. Recovery and destroy There may be a

Experimenting with compression off

Now that the new storage is in place, I thought to test with compression on and off. Perhaps also use both lz4 and zstd. For reference, this is one of a series of posts regarding compression testing on zpools: Experimenting with compression off – you are here Experimenting with compression=lz4 Experimenting with compression=zstd Compression results My plan: create three zpools of two mirrored devices and test. There will be three posts: compression off,

Leveling out the NVMe cards on the adaptors

Leave a Comment / hardware, nvme / By /

I recently obtained two 4TB NVMe cards and two PCIe adapters, each of which holds two NVMe cards. This is what they looked like fully loaded: The thinner NVMe is the new 4TB card, and the thicker card is the 1TB card, with heatsink, which I’ve had for some time. Yesterday I noticed the NVMe cards were not parallel with the adaptor. Earlier today, I fixed that. First, let’s look at the angles.

Today I was trying to access my Dell 730 (r730-01) via the remote console. I failed. Twice. First and expected failure First, this was usual and expected. It’s been a problem both at home and at work. It is the inability to access the console via https using the hostname This is what I see: I can get in via IP address though. Second and new-to-me failure Next, after logging in via IP
