- Verify lscgctl works after running lssetup
- Retry with more slices (-c 10) if first attempt fails
- Add detailed logging to debug setup issues
- Add time.sleep() to give lssetup time to initialize
- Provide clear error messages if setup fails
- Pass --io parameter to lscgctl with bytes/sec value
- Convert ioLimitMBPS from MB/s to bytes/s for lscgctl
- Update log message to include I/O limit information
- Add note about systemd io controller delegation requirement
- Add test to verify LiteSpeed Containers is actually configured
- Check for 'You must configure LiteSpeed' error in lscgctl output
- Run lssetup with proper flags when configuration is needed
- Fixes issue where lscgctl exists but LiteSpeed Containers not configured
Detect RHEL 8, AlmaLinux 8, Rocky Linux 8, and CloudLinux 8 systems and provide
clear instructions when cgroups v2 needs manual enablement.
These systems have cgroups v2 backported to kernel 4.18 but it's disabled by
default. When detected without cgroups v2 enabled, the system now:
1. Detects RHEL 8 family by checking /etc/redhat-release
2. Verifies if cgroups v2 is mounted (checks 'mount' output for 'cgroup2')
3. If not enabled, logs detailed instructions:
- grubby command to add kernel parameter
- Reboot instruction
- Verification command
- Clear step-by-step guide
Changes:
- _check_rhel8_cgroups_v2(): New method for RHEL 8 family detection
- _ensure_cgroups_enabled(): Calls RHEL 8 check before general checks
- check_cgroup_support(): Returns RHEL 8 status in support dict
- rhel8_family: bool (detected RHEL 8 family)
- rhel8_needs_enablement: bool (cgroups v2 not mounted)
- os_name: str (full OS name from release file)
OS Support Status:
✅ Ubuntu 20.04+ - Native cgroups v2 (kernel 5.4+)
✅ RHEL/Alma/Rocky 9+ - Native cgroups v2 (kernel 5.14+)
⚠️ RHEL/Alma/Rocky/CloudLinux 8 - Needs manual enable (kernel 4.18 backported)
