Session Summary
Investigated a "CS-SERVER running slow, check for infections" report for Cascades of Tucson.
Resolved CS-SERVER to GuruRMM agent c39f1de7-d5b6-45ae-b132-e06977ab1713 (online, agent
v0.6.66) and ran a multi-pass health/security probe over RMM (PowerShell as SYSTEM). The box
is NOT resource-starved: 48 GB RAM (~72% free), CPU avg 16-26%, C: 151 GB free / D: 490 GB
free, 10-day uptime, no unexpected-shutdown or crash events. So slowness is not RAM, CPU, or
disk-space exhaustion.
Root cause is a degraded RAID-1 array. Dell OMSA (omreport) on the box shows Physical
Disk 0:0:3 (WDC WD3200BEVT, 320 GB SATA laptop drive) as Critical / Removed, and Virtual
Disk2 (RAID-1, = Windows Disk 1 = C:) as Non-Critical / Degraded. The C: mirror (OS / AD /
SQL / page file) is running on a single surviving 320 GB Hitachi 5400 RPM laptop drive (0:0:2)
with zero redundancy. The healthy D: volume is a separate RAID-1 of two 1.2 TB SAS drives
(Virtual Disk0, OK). A 1.2 TB SAS disk (1:0:4) sits "Ready" but is the wrong size/type to
rebuild the 320 GB SATA mirror, so no auto-rebuild occurred. Controller is the basic SAS 6/iR
Integrated (3 Gbps, no real cache) — degraded mirror on a slow laptop spindle fully explains
the slowness, and combined with the documented no-backup / single-DC posture it is a
data-loss emergency.
Infection check came back clean. CS-SERVER is NOT enrolled in the ACG GravityZone/Bitdefender tenant (only 3 Cascades endpoints there: LAPTOP-DCQNDJJ2 + RECEPTIONIST-PC). Windows Defender is replaced by a third-party "Endpoint Protection Service" (Syncro-managed) with no detected threats. IOC sweep (external connections, scheduled tasks, Run keys, recent temp/ProgramData binaries) found only legitimate management/EDR tooling. Notable: the box carries the previous MSP's leftover Datto stack (Datto RMM/CentraStage + Datto EDR/Infocyte) on top of ACG's Syncro
- GuruRMM + ScreenConnect + KPAX — multiple overlapping agents thrashing the degraded spindle.
Discussed the SSD migration question: the rebuild-then-swap approach (replace failed member with SSD #1, rebuild, then swap the other member for SSD #2) is valid and will materially help (workload is random-I/O bound; SSDs win big even at the controller's 3 Gbps cap), but with hard caveats: back up/image C: BEFORE any rebuild, use enterprise SATA SSDs >= 320 GB (no TRIM through this controller), and it is a band-aid on EOL hardware — the planned DC migration is still the real fix. Mike then installed ACG's cloud backup (MSP360/CloudBerry to the ACG-backup server) and started a backup, addressing the #1 prerequisite.
Second task: Howard had lost the OpenVPN password for his pfSense user. Vault held only the
pfSense admin GUI login (no per-user OpenVPN credential), and pfSense stores user passwords as
bcrypt (unrecoverable) — so a reset, not a lookup. Drove the pfSense web UI from CS-SERVER via
RMM (CS-SERVER can reach 192.168.0.1:443/22; OpenVPN local-DB user is Howard, userid 0).
Reset the password to the value Howard supplied using pfSense's native
local_user_set_password() via the Diagnostics PHP-exec endpoint (surgical — preserves groups
/cert/OpenVPN bindings), verified it with local_backed() returning AUTHOK, vaulted it, and
synced.
Key Decisions
- Used Dell OMSA
omreport storage pdisk/vdisk/controllerrather thanGet-PhysicalDiskto see real drive health —Get-PhysicalDiskonly shows the PERC virtual disks (both "Healthy") and hides the failed member behind the RAID controller. - Reset the pfSense password via the Diagnostics PHP console calling
local_user_set_password()local_user_set()+write_config(), instead of scripting the user-edit form POST. The form approach requires resubmitting every field (groups, cert) and risks wiping the user's OpenVPN cert/group bindings; the PHP API touches only the password.
- Did not use SSH for the reset: pfSense SSH presents the admin menu and Windows OpenSSH cannot feed a password non-interactively, so the HTTPS GUI + curl path was the only scriptable option.
- Verified at every write step (read user list before changing;
local_backed()auth test after) rather than trusting the OKRESET echo — which caught that the first reset attempts had silently failed (see Problems). - Left the leftover Datto/CentraStage/Infocyte agents in place — cleanup is a separate, lower-priority decision, not done this session.
- Held all CS-SERVER changes: only read-only diagnostics were run on the server; the drive swap must wait until the first full backup completes and verifies.
Problems Encountered
- Windows
curl.exeinvoked from PowerShell strips embedded double-quotes from--data-urlencodearguments (CommandLineToArgvW), silently mangling the POST body. My pfSense PHP payloadecho "PHPRUNS-OK";arrived asecho PHPRUNS-OK;-> PHP "Undefined constant", and the multi-line reset PHP hit a parse error so it never executed (no partial change). Fixed by writing the PHP with single-quotes only, building$via[char]36, on a single line. Cost ~4 wasted RMM round-trips. Logged to errorlog.md with--friction. - pfSense
diag_command.phpdispatches the PHP branch on the submit button valuesubmit=EXECPHP(not on field presence); omitting it returned the bare form. Confirmed by GETting the form and enumerating field names (txtPHPCommandtextarea +submit=EXECPHP). vault-helper.sh newfailed withModuleNotFoundError: No module named 'yaml'— thepylauncher lacked PyYAML. Fixed withpy -m pip install pyyaml(installed 6.0.3), then the entry created/encrypted/verified cleanly.- First RMM health probe returned
interrupted("Agent restarted during execution"); simply re-dispatched and it completed. The big probes exit 1 because individualGet-WinEventno-match branches and the client-onlyroot\SecurityCenter2namespace throw on a Server OS — cosmetic, the useful sections still print.
Configuration Changes
- pfSense (192.168.0.1) — Cascades: reset local user
Howard(userid 0) OpenVPN/GUI password.write_configrevision committed on the firewall ("Reset Howard local/OpenVPN password (ACG remote support)"). No other pfSense settings touched. - Vault (new file):
clients/cascades-tucson/pfsense-openvpn-howard.sops.yaml(kind vpn, encrypted, pushed). - Howard-Home:
py -m pip install pyyaml(6.0.3) — PyYAML was not previously present for thepylauncher; needed byvault-helper.sh. - errorlog.md: one
--frictionentry (curl.exe double-quote stripping). - No changes made on CS-SERVER itself (read-only diagnostics only).

Pending / Incomplete Tasks
- Backup must complete AND verify before any drive work. Confirm the MSP360 job is image-based / bare-metal + system-state (not file-only) for DC recoverability, and that it finished a first full. (Offered to check progress via RMM — not yet done.)
- RAID remediation: either source a matching 320 GB+ SATA SSD/HDD to rebuild the C: mirror, or (preferred) migrate C: to enterprise SATA SSDs via rebuild-then-swap — only after backup verifies. The existing 1.2 TB "Ready" disk cannot rebuild the 320 GB mirror.
- Strategic: accelerate the planned DC migration off the EOL R610; still single-DC + the array is now actively unprotected.
- Optional: clean up leftover previous-MSP Datto RMM (CentraStage) + Datto EDR (Infocyte) agents to cut I/O churn.
- Consider enrolling CS-SERVER into GravityZone (currently no Bitdefender coverage on the DC).
