2600 × 2600 mm (8'6" × 8'6") room with a 30" PR-5000 — is this actually usable in real life?

I'm planning a dedicated strength-training room that is exactly 2600 × 2600 mm (about 8'6" × 8'6").

The setup I'm currently planning is:

  • REP PR-5000
  • 30" depth
  • 93" uprights
  • 4-post
  • Flip-Down Safeties 2.0
  • standard J-cups
  • REP AB-3000 2.0 FID bench
  • REP Colorado Short Bar, 15 kg

The rack will be anchored to the concrete floor.

The short bar is an important part of the plan. I'm deliberately not using a standard 2200 mm / 7'3" bar.

The Colorado Short Bar is:

  • 1829 mm / 72" overall length
  • 1308 mm / 51.5" between the sleeves
  • 226 mm / 8.9" loadable sleeve length per side
  • 28.5 mm shaft
  • 50 mm sleeves
  • 15 kg
  • rackable in the PR-5000

With an 1829 mm bar in a 2600 mm-wide room, if the bar is centered there is approximately 386 mm / 15.2" between each end of the bar and the wall.

The main exercises I'm planning around are:

  • bench press
  • back squat
  • deadlift
  • pull-ups

I can work out whether all of this physically fits from the dimensions. What I'm trying to understand is something different: is a gym like this actually practical and comfortable to use, or does a room this small become frustrating despite everything fitting on paper?

I'm particularly interested in hearing from people who have actually trained in an 8 × 8, 8 × 9, 9 × 9 ft or similarly small room with a full power rack.

Some things I'd like to understand from actual experience:

  • Is roughly 386 mm / 15" of clearance between the end of the bar and the wall enough for loading and unloading plates without it becoming annoying?
  • Is a 30" deep power rack reasonable in a room this size?
  • How much clearance around the rack do you actually need in everyday use?
  • Is positioning and moving the bench manageable?
  • Are there normal operations or exercises that seem fine on a floor plan but become difficult once you actually start training?
  • If you've used a similarly small home gym, what worked well and what would you change after living with it?

I'm mainly looking for first-hand experience rather than calculations. The dimensions tell me that the equipment can fit; what I don't know is whether the resulting gym will actually be pleasant to use several times a week.

If you have a similarly compact setup, photos and exact room/rack dimensions would be very useful.

Intermittent ARP failure for FreeBSD VNET jails behind VXLAN on Arista DCS-7150

────────────────────
SETUP
────────────────────
⠀
FreeBSD 15.1 with four VNET jails on the same L2 segment:
⠀
172.18.10.0/24
VLAN 1010
VXLAN VNI 10010
⠀
Jails:
⠀
• 172.18.10.10 — PostgreSQL (dns_pg_001)
• 172.18.10.11 — PowerDNS Authoritative
• 172.18.10.12 — PowerDNS Recursor
• 172.18.10.13 — Kea DHCP
⠀
The jails are connected locally through a FreeBSD ng_bridge.
⠀
The VXLAN VTEP extends this L2 segment to an Arista DCS-7150S-24-F running EOS 4.23.15M-2GB.
⠀
Arista SVI:
⠀
172.18.10.1/24
⠀
────────────────────
CONFIRMED OBSERVATIONS
────────────────────
⠀
The intermittent problem mainly affects 172.18.10.10.
⠀
After a period of inactivity, 172.18.10.10 has sometimes become unreachable from the Arista:
⠀
ping 172.18.10.10
⠀
Result:
⠀
100% packet loss
⠀
During such a failure, the Arista VXLAN MAC table contained:
⠀
589c.fc10.cfbe -> Vxlan1 -> 172.17.1.10
⠀
while the Arista ARP table did not contain a usable entry for:
⠀
172.18.10.10 -> 589c.fc10.cfbe
⠀
Packet captures showed that:
⠀
• the Arista ARP request reached the jail
• the jail generated an ARP reply
• FreeBSD encapsulated the reply into VXLAN with VNI 10010
• the encapsulated packet reached the Arista side
• no dynamic ARP entry for 172.18.10.10 appeared on the Arista
⠀
Similar behavior was also observed with 172.18.10.11, so the symptom is not unique to the PostgreSQL jail.
⠀
The jail MAC addresses are fixed.
⠀
────────────────────
WORKAROUND TESTED
────────────────────
⠀
I configured static ARP entries on the Arista.
⠀
For example:
⠀
arp 172.18.10.10 589c.fc10.cfbe arpa
⠀
After the VXLAN MAC entry for .10 was absent, Arista showed:
⠀
172.18.10.10 589c.fc10.cfbe Vlan1010, not learned
⠀
In that state:
⠀
• .10 was reachable from the T640 after more than 15 minutes of inactivity
• a subsequent ping from the Arista succeeded
• after that ping, Arista again showed 589c.fc10.cfbe dynamically learned on Vxlan1
⠀
The same recovery from “not learned” was also reproduced with .11.
⠀
────────────────────
INTERPRETATION / QUESTION
────────────────────
⠀
My current interpretation is that static ARP avoids dependence on the dynamic ARP learning/relearning behavior that previously caused loss of reachability, while VXLAN MAC learning remains dynamic.
⠀
I do not know whether static ARP is the usual workaround for DCS-7150 / EOS 4.23 with static VXLAN, or whether there is a standard configuration or known platform-specific fix for reliable dynamic ARP learning in this setup.
⠀
Has anyone seen this behavior on DCS-7150/FM6000 or EOS 4.23?
⠀
What is the usual solution?
