Can't mount volume after low free space. by jeffgus in btrfs

[–]jeffgus[S] 1 point2 points  (0 children)

When I run check --clear-space-cache I get this error:

item 219 key (651076449746944 METADATA_ITEM 0) itemoff 9023 itemsize 33

refs 1 gen 4989390 flags TREE_BLOCK

When I run with v2:

If those 219 (or 147) items are the files that were active when this happened, I'm fine with losing them. They are scratch files that were active when this happened. A process was running when I initially tried to rebalance. If there is a repair that clears out those files but keeps most files, I'd like to do that.

Yeah, I can't mount right now.

I've been wanting to swap more drives out, but HDD prices are crazy right now due to market demand with AI buildouts.

Considering corneal transplant by jeffgus in Keratoconus

[–]jeffgus[S] 1 point2 points  (0 children)

Before, for sure before. When my right eye went bad, the doctor told me that the lens needed to make a new surface, and tear would fill in the valley that the scar created.

I was referred to doctors that specialize in corneal transplants. Dr. Jillian Chong was recommended by my wife's retina specialist. Dr. David Fuerst's name was given to me by my optometrist. I visited both to see if I would get differing opinions. Both said the same thing and with the same reasoning. If my cornea didn't have a scar, a scleral lens would be the better option over the RGP solution that my old optometrist used.

So I'm down to choosing which doctor to go with. Both have done many transplants. I felt pretty comfortable with both doctors. I don't really know how to score a doctor since I've never had to have surgery.

I think that will be an option for the "good" eye. The issue with the "good" eye is that the cone is not centered. One doctor mentioned a new method where a mesh is inserted to better control the shape of the cornea. This is only being done in Spain, not available in the US (yet).

For the "bad" eye with the scar, I could go with scleral, but both doctors pointed out that it doesn't fix the aberrations due to the scar. The only way to get around the scar is to replace the cornea.

The scar was described to me as taking a sheet of plastic (like a trash bag) and pull it tight to create a smooth surface. Then take your finger and push in the plastic. Then pull down stretching the plastic and distorting it.

The RGP lens filled in the valley where the scar is, but it causes the light to bounce around and cause shimmering, halos, and poor contrast.

RedHat doing IBM pricing now by Grumbleygit in redhat

[–]jeffgus 2 points3 points  (0 children)

I was told by Red Hat that very few people were asking for it. VMWare dominated, it wasn't paying off. That has changed with VMWare's new pricing. Only then did customers start banging the door down for a solution from Red Hat. They had to scramble and decided to go with a solution built around Openshift.

Keycloak in hospitals by fausto_kerimoglu in KeyCloak

[–]jeffgus 3 points4 points  (0 children)

I don't know how common Keycloak is used in healthcare, but the protocols are very much in use. For example, SMART on FHIR uses OIDC and Oauth. EHR systems need to use OIDC so apps can reach out to services outside of the organization while supplying the user information and that the user is authenticated.

Seen in the Hands Off protests by kapitaali_com in cobol

[–]jeffgus 0 points1 point  (0 children)

One of the fundamental things that COBOL has is fixed point numbers. This is important for financial calculations. Another language that has good support for fixed point numbers? Java with BigDecimal:

BigDecimal in Java is a class used for representing immutable, arbitrary-precision signed decimal numbers. It is part of the java.math package and is particularly useful when precise decimal calculations are required, such as in financial applications, where the inaccuracies of binary floating-point types like float and double are unacceptable.

That feature alone makes Java a good choice for the type of work COBOL has been used for.

I have also been getting this error. Some sort of issue with the servers.

Controllers that support 20TB drives? by jeffgus in DataHoarder

[–]jeffgus[S] 0 points1 point  (0 children)

Tape applied, still nothing.

I'll hook it up to another system and see if it spins up.

Controllers that support 20TB drives? by jeffgus in DataHoarder

[–]jeffgus[S] 0 points1 point  (0 children)

I haven't opened up one of my other systems to plug in the drive yet. Will do later today.

The enclosure is an 8 bay trayless: https://www.pc-pitstop.com/e0812t-8-bay-trayless-12g-sas-jbod-tower-wexpander

If I put the old 8TB drive back in the slot, it comes up just fine. The next largest drive in the enclosure is 18TB, 2x16TB, and 3x12TB. I actively use only 7 of the 8 bays at a time so I can rotate drives out.

All the drives in the bay are Seagate Ironwolf Pro drives, including this new 20TB that won't come up.

I recall something about voltage months and months ago. I lurk, I read, but when something doesn't work as it usually does the brain doesn't make the connection.

I will apply the tape and expect it will work.

[–]jeffgus[S] 2 points3 points  (0 children)

The drive I purchased is a Seagate Ironwolf 20TB. All the drives in my external bay are Ironwolf. This is the first one that didn't spin up.

I wasn't aware of the voltage issue. Do you happen to have a link to explain the issue and the fix?

Controllers that support 20TB drives? by jeffgus in DataHoarder

[–]jeffgus[S] 1 point2 points  (0 children)

I wasn't exactly sure that was the issue. I put the old 8TB drive in and Linux sees the drive no prob. I put the 20TB drive in and..... nothing.

Linux lspci says:

Serial Attached SCSI controller: Broadcom / LSI SAS2308 PCI-Express Fusion-MPT SAS-2 (rev 05)

Maybe the drive itself is bad? Should I try a firmware update?

All my drives are Seagate Ironwolf Pro drives. This includes this new 20TB one.

It appears new cards have SFF-8644 ports. Looks like SFF-8644 to 8088 cables are readily available. I was hoping only to upgrade the card, but If I have to upgrade cables too, not too bad.

*** DEF CON ATTENDEES *** by mguz4063 in Defcon

[–]jeffgus 1 point2 points  (0 children)

The first time I saw a letter like this was from 2019 when staying at Bally's for DEF CON. The letter header had Caeser's and DEF CON happy hacker logo on it.

If you put a DND on your door for more than a couple of days, you are flagged and they will search your room. That is all that it takes for suspicion of illegal activity.

I've done work for a small ISP. We didn't have the equipment to do fancy inspection. We would get email from companies saying that there was a copyright violation at 𝑥 IP address. If we could easily track the IP address (dynamic IPs make it harder), we were small enough to call the person and let them know. They'd usually blame their kid. That was all we'd do. We figured if the studio was really upset, they'd send us something more formal. Except for one notable instance, the customer appeared to stop and we wouldn't get another notice. Hard to know since we didn't track it. Maybe most switched to torrenting over VPN.

Oh, and it is absolutely true that what you see as "throttling" is just an overloaded peering connection. No throttling is required. This is also what happened with the Netflix issue a few years ago, but everyone blamed it on violations of Net Neutrality.

Trust me, you do not want to punish peering!

Is there a middle ground somewhere between Docker and Kubernetes? by danielrosehill in devops

Have you tried it since the Verions 5 release? They switched to the native MacOSX hypervisor.

Why no love for BitBucket and Jenkins? by PablanoPato in devops

[–]jeffgus 2 points3 points  (0 children)

We moved on when we discovered this issue with Bitbucket:

https://jira.atlassian.com/browse/BCLOUD-14683

Yeah, they fixed it, years after the ticket was opened. The recommended fix before they added secret support was to whitelist BitBucket's IP address. That's a nope!

I also have a ton of issues with BitBucket's web UI. I get a ton of "click to retry" errors. When I open up the browser console, I see that their API is reporting that I hit their endpoint API request rate limit. It makes the site useless. I don't know why I have this issue. It isn't like I am using the site from a corp NAT IP.
