Troubleshooting
Before contacting support, check these common issues:
Connection Problems
| Problem | Solution |
|---|---|
| Cannot SSH into the server | Check your SSH key is correct. Try ssh -v user@ssh.abi.am for verbose output. |
| Connection timeout | ssh.abi.am is accessible from the internet – no VPN needed. Check your network connection and try again. |
Permission denied (publickey) | Your SSH key is not on the server. Email IT to add it. |
Slow Internet at the Office
- Test local network speed: Copy a large file (>100MB) from a local server. If slow, the WiFi may be the issue – try reconnecting.
- Test Armenian network speed: Run a speed test at Speedtest.net. Should be >250 Mbps.
- Test international connectivity: Run a speed test at librespeed.org using a Western European server (Amsterdam, Frankfurt). If slow, the issue is upstream at IIAP.
Slurm Issues
| Problem | Solution |
|---|---|
Job stuck in PD (pending) | Resources are busy. Check with sinfo if nodes are available. Reduce resource request if possible. |
| Job failed immediately | Check the log file for error messages. Common causes: typo in script, missing input file, wrong path. |
Exceeded job memory limit | Your job needed more memory than requested. Increase --mem. |
CANCELLED … DUE TO TIME LIMIT | Job took longer than expected. Increase --time. |
See the full Slurm Troubleshooting section for more.
Disk Space Issues
# Check your home directory usage (~12G quota) du -sh /mnt/home/$USER/ # Check your personal workspace (~100G quota) du -sh /mnt/nas0/user/$USER/ # Check project directory usage du -sh /mnt/nas1/proj/your_project/ # Check overall filesystem space df -h /mnt/home /mnt/nas0/user /mnt/nas1/proj /mnt/nas1/db
If you are running out of space:
- Remove old/temporary files and intermediate results
- Clean Conda caches:
conda clean –all - You do not need to manually compress files – the storage uses ZFS with transparent compression
Frequently Asked Questions
Q: How do I change my password?
A: *TODO: Describe password change procedure. If passwords are managed via LDAP, the admin changes it. If there is a self-service option, document it here.*
Q: How do I add someone to my project?
A: Contact it-support@abi.am with the person's username and the project name.
Q: Where should I store my data?
A: Use your project directory (/mnt/nas1/proj/<project>) for research data. Use /mnt/nas0/user/<your_username> for personal experiments and data. Keep your home directory (/mnt/home) for configs and small scripts only (~12G quota). See Storage.
Q: Can I install software myself?
A: Yes, using Conda. See Installing Software with Conda. For system-wide installations, request them via IT.
Q: What happens when my job finishes?
A: Output files are written wherever your script specifies. The console output goes to the log file specified by --output. Check it with cat log/yourjob_<jobid>.log.
